    The invention relates to a contactor comprising a housing provided with a plurality of parallel sections, each of which combines a switch installed in a controlled circuit, the movable contact of which is set in motion when the common rocker moves. At least one of these switches is made in the form of a sealed monostable microswitch having an abrupt shutdown characteristic, whose own internal terminals are electrically connected to two external connected terminals located in each of the mentioned sections. These sections are located in the upper part of the housing connected to the base.
    These contactors are used in those cases when the working capacity of the contactors may be violated by the conditions of their use, especially when used in low voltage control circuits.
    In the known contactor, small switches are actuated, installed in sealed enclosures (mini or micro switches), by means of electromagnets, which are used in low voltage circuits. Fixing small microswitch housings in a predetermined position is difficult, and they are connected to terminals that, in order not to disorient installers, must be of the same shape that usually occurs in contactors or similar devices designed for higher currents and containing power switches. .

    In order to comply with the requirements, it is imperative that microswitches perform the functions of closure or opening or combined functions depending on the wishes of the customer; these functions must be protected from subsequent change by an unqualified customer.
    The purpose of the invention is to increase operational reliability.
    This goal is achieved by the fact that between two open and opposite cavities of one section, intended for installation of a microswitch and external connecting terminals, there is an isolated recess, which serves for the actual installation of a microswitch, having exits on one side close to the arm part and on the other side close to means of holding in position, capable of receiving on one side an insulating abutment, equipped with conductive parts, terminating in the terminals of the microswitch, and with nother side electrical connection between each terminal and the respective actuator conductive portion. The specified notches are closed with a contactor base.
    Fig. 1 shows a partial section of a contactor with a plane passing through the axes of two terminals of a circuit controlled by a microswitch; see, 2, too, side view; on fig.Z - microswitch connected to the connecting support; Fig. 4 shows the means used for fixing and connecting the microswitch, the cross section; Fig. 5 shows the outer connecting terminal; on fig.b and 7 - microswitches intended for carrying out the functions of closing and opening of circuits, bottom view; Fig. 8 shows a control rotor used to control two microswitches located in the contactor; Fig. 9 is a perspective view of an auxiliary contact housing designed to implement the invention, which can be connected to an independent contactor,
    The contactor 1 comprises a housing 2 formed by means of a base 3 and a housing 4. The contactor is designed to actuate switches 5-8 located respectively in one of the insulated sections 9-12, each intended for its own electrical circuit. Some switches are located near the central axis XX1. Pins 14 and 13 of microswitches 6 and 7 are integrated with the case and are fixed. The movable contacts 15 are located on the yoke 16, which is connected to the movable reinforcement 17 of the electromagnet 18 installed in the base. The other two microswitches 5 and 8 are made in the form of microswitches-inverter 30 and contain their own terminals 31-33.
    The beam has grooves 19-21 that allow the baffles to be bent.
    the bodies located between the sections and two lateral extensions 22 and 23, extending into the side opposite sections 9 and 12. The bar 16a moves in two central sections 10 and 11.
    Each extension extends into the space between the two external connecting terminals 25 and 26 - a recess 27. This recess is open in its upper part 28, in which the extension 22 moves, and in
    the lower part 29, which can be closed by the base 3 when it is assembled with the casing.
    The housing 35 of the microswitch 30 is attached to its own terminals 31-33, made on a rectangular printed circuit board
    a mold 34 having five holes, preferably metallized, and forms a sub-block (knot) 40, ready for subsequent assembly. Two holes 36 and 37, located along the edges, are offset relative to the symmetry axis YY of this printed circuit board. The opposite ends of this board have constrictions or protrusions 38 and 39. The opening 29 of the recess 27 comes out close to the two open tabs 41 and 42, which
    they are integral with the casing 4. These tabs are of a rather small thickness, which gives them a certain elasticity. Each tongue has a beveled protrusion 43, adjacent to a small groove 45.
    The assembly 40 in the recess 27 is mounted in the direction of the arrow C, bending the tabs until the protrusions 38 and 39 enter the grooves 45. The dimensions of the protrusions and grooves correspond to each other, with the result that the assembly takes the correct position after installation relative to the plane P-P symmetry of the notch and corresponding elongation of the rocker arm.
    Above each of the slots 45 in the casing wall 46, which supports the tongue 41, there is a passage 47 which communicates the external open volume 48 or 49 with the corresponding recess 27.
    External volumes 48 and 49 are designed to position external connection terminals 50 and 59 for electrically connecting the own terminals of the microswitch 30. to the external electric circuit elements.
    The connecting terminal 50 shown in FIG. 5 is made in the form of an electrically conductive part 70 having a contact pad 51 provided with a threaded hole into which a screw 52 with a tab is screwed. The extension 53 of the terminal enters the recess 27 to contact the conductive area of the board 34. For this purpose, the extension 53, which has a 90 ° triple bend for passage 47, is directed perpendicularly to the plane of the board and has a smaller tooth 54 for penetration into one of the metallized holes 37 and 36. This penetration is carried out by appropriate displacement when pre-installing the external terminals and inserting the microswitch assembly into the recess along arrow C and snapping onto the projections 43. To avoid erroneous orientation 40. la that is not in contact with the end 66 of the pressure device 60. The protrusion 65 is in contact with the metal part 61 connected with extension 22. The recess 27 in the microswitch 30 can be placed closer to one end of the board than the other.
    Since, for reasons of economy, the two terminals 50 and 59 are identical, the teeth of the two extensions are rotated 180 ° relative to the P-P center plane. therefore, the metallized holes 36 and 37. in which these teeth enter are offset from the central axis of symmetry YY of the printed circuit board.
    After this installation, the teeth 54 are soldered to the tracks of the printed circuit board (FIGS. 6 and 7), which have entered the holes 38 and 37 in place. Due to the curved configuration of the terminals, which are fixed in the grooves 55 and 56 of the adjacent partitions, no mechanical forces are communicated to the circuit board when the screws are screwed in (Figure 5). In addition, the teeth are sufficiently rigid to ensure that the position of the microswitch is maintained in the event of a displacement of the support lugs.
    Depending on the type of operation, it may be necessary to either open (O) the circuit or close it (FJ, when energizing an electromagnet, in these cases use the corresponding nodes 40o. 40p and the 34o-34p boards of which An appropriate external terminal is located at one of the two terminals 31 and 32 of the microswitch (Figures 5 and 7). The letters O and F will appear on the printed circuit boards to facilitate the identification of the required function of the 40o or 40p microswitch assembly.
    The swiveling and elastic control lever 60, mounted on the axis in the microswitch housing (Fig. 3) and opposite the recess 28, is brought into operation by means of a metal pusher 61 connected to an extension 22. The pusher 61 is formed by a thin elastic plate, the end 62 of which secured in this extension, while the other end 63 resiliently rests against the abutment 64 of the extension 22 of the pusher under the action of a slight prevailing deformation (Fig. 8).
    A protrusion 65 of this plate, located opposite the lever, informs the latter of the rotational movement when the reinforcement is pulled in the direction of arrow I. Thanks to the construction described, the accidental departure of the rest position of the end 66 of the lever 60 can be compensated in the same way as the accidental excess of the theoretical movement of the reinforcement and rocker arm.
    Switches in sealed enclosures or microswitches are located in the side sections 9 and 12 of the apparatus in order to facilitate the creation of a common rocker 16 that controls all the switches, facilitate installation and electrical connection of the nodes 40. The appearance of this rocker arm (Fig.8) depends on additional requirements - sufficient rigidity, high electrical insulating properties and controllability when moving.
    The insulating and guiding groove 77 serves to accommodate the protrusion of the partition 20. The lateral edge 78 serving to guide the movement enters the groove of the partition 21, the portions of the partitions 79.83, 81 and 82 provide, together with the partitions connected to them, an increase in the leakage lines, which is necessary when used in two central sections 84 and 85 of movable bridges 15. belonging to powerful switches 6 and 7. whose operating voltage and current are increased compared with microswitches.
    The grooves 77a and 77b are intended for purposes similar to those performed by the grooves 77, but for notches 27, 28 and 24.
    A symmetrical arrangement with respect to the axis XX1 of two switches 6 and 7 of the first type and two switches 5 and 8 of the second type ensures the distribution of the forces applied to the rocker when the electromagnet is excited and imparts sliding during movement as well as the absence of jamming during compression of the return spring of the contacts.
