    FIG. 1 shows a single pole switching device switch in the switching position, front side; in fig. 2- the same in the off position after manual unlocking; in fig. 3 - the same in the off position after free unlocking; in fig. 4 shows section A-A in FIG. 1. The multi-pole overload current switch consists of three separate single-pole switches, each of which is placed in a corresponding housing. The body of the control 1B as a two-armed lever and two connecting strips 2 and 3 protrude from the body. In the body, the control body is mounted inclined on axis 4. An extension spring 6 acts on the arm 5 of the control body on the side of the body. In the arm 5 there is an elongated groove 7 in which the axis 8 of the lever 9 is placed. In the arm 5 a spring 10 is mounted which rests on a disk 11 adjacent to the upper end of the lever 9. Through the axis 12, the levers 9 and 13 pivotally connect and form a crank joint. . The lever 13 consists of a sheet metal part (only the rear bend is visible, shown in section). The lever 13 has a transverse part 14. The lever 9 through the axis 15 is pivotally connected to a locking lever 16, which engages the transverse part 14 with a protrusion 17. In the switching position shown in FIG. 1, the locking lever 16 locks the levers 9 and 13 of the crank link. In this position, they form a strong link. The spring 18 mounted on the axis 15 rests with its shoulder on the lever 9, and with the other shoulder into the hole 19 of the lock lever 16 and holds it in the lock position (Fig. 1). In the locking position, this rigid crankshaft with arm 5 of control 1 forms a crank lever. The lever 13 is bolted 20 pivotally to the U-shaped contact holder 21, which is mounted with the help of the axis 22 and can be rotated in the housing. A bolt 23 passes through a U-shaped holder 21, with which a contact lever 24 is mounted obliquely on the holder 21. With a bolt 23, the latch 25 is pivotally connected to the holder 21, which has a locking protrusion 26 and a beveled angle 27. To the upper end of the latch 25 a tension spring 28 is attached, the upper end of which is fastened with a bolt 29 located in the casing. The upper end of the latch 25 works together with the protrusion 30 of the arm 5 of the control body 1. Inside the contact holder 21 is placed a spring 31, which unites at one end into the contact lever 24 and at the other end into a transverse part 14. Under the action of the spring 31 (Fig. 1) the contact 32 of the lever 24 is pressed against the fixed contact 33 of the connecting bar 3. Thus, the spring 31 creates a contact pressure. The contact lever 24 has a shoulder 34, which in the "off" position (Fig. 2 and 3) under the action of the spring 31 abuts the axis 22. The contact lever 24 is connected by a flexible conduit 35 to the end of the coil 36 of the electromagnet 37, the other end of the coil by flexible wire 38 connected to a bimetallic nlashina 39 fixed to the connecting bar 2. The bimetallic platitype 39 has an installation bolt 40 that can act upon the engaging lever 41 when bending the bimetallic plate 39. The lever 41 is mounted in the housing using the axis 42. On his. the lower arm acts on the spring 43. The lever 41 on the upper arm deflects the locking lever 16 to a non-operating position. On the other hand, the upper arm of the lever 41 can be affected by the contact holder 21. On the left end of the core 44 of the electromagnet 37 is placed the adjusting screw 45, which, when the core is wired into the electromagnet, excites it and presses the lower lug of the lever 41. The core of the electromagnet has a shoulder 46, which can work together with the lever 47, which can be rotated 48 When the lever arm 47 is propped in an hour hand, the arm 49 of the lever 47 presses the contact lever 24 and thereby disconnects the contacts 32 and 33. Due to this, when opening 1: o): tpk-10z and, especially, with a short circuit Acceleration current limiting effect is achieved. The stop protrusion and the beveled recess of the latch 25 have the ability to interact with the stop 50. Each lever 41 is made in a U-shape (Fig. 4) and has rectangular grooves 51 (Fig. 1-3), which serve to accommodate the fitting 52 (Fig. . four). The lever 41 of the middle single-pole overcurrent switch is rigidly fastened to the connecting part 52 with a pressure screw 53. The connecting part 52 is made of a non-conductive material and its cross-section corresponds to a straight section of the groove 51. Both ends of the connecting part are made so that they fit a gap into the corresponding rectangular grooves of both levers 41 of the outer side single-pole overcurrent switches (Fig. 4). Item 52 interconnects the separate three switches located in line with the axis 42. Each cover of each of the three single-pole switches consists of, two halves 54 and 55, connected in the usual way to each other. In addition, separate $
    the covers of three single pole non-switches are firmly connected to each other.
    Both nolovnny 54 and 55 at the location of the connecting parts 52 have grooves 56 and 57. The ends of both external axes 42 are mounted movably in the corresponding grooves of both halves 54 and 55. When an overload current appears in one single-pole switch, only this switch is disconnected due to the presence of there is a certain gap in it, and the remaining switches are disengaged by the levers and the connecting piece from the action of the contact carrier, which is under the action of the spring.
    The force of the spring acting on the latch raises it together with the contact holder and thereby disconnects the contacts, the contact holder simultaneously rotates the related lever together with the connecting piece. Due to this, the connector also tilts the levers of the other single-pole switches to turn them off. When switched on (Fig. 1), the current in the presented single-pole switch from the attachment plate 2 goes through bimetallic plastic 39, flexible wire 38, coil 36, flexible wire 35, contact lever 24 and contacts 32 and 33 to the connecting bar 3. When overcurrent occurs In this one-pole switch, the bimetallic plate 39 is bent counterclockwise, while the adjusting bolt 40 presses the lower arm of the lever 41 and it tilts counterclockwise so that the upper lever lengthens the locking lever 16 in hours The aces arrow to the neutral position, in which its protrusion 17 leaves the engagement with the transverse part 14.
    Under the action of the spring 31n, in particular, the spring 28 bends the crank link, which comes from the levers 9 and 13, due to this, the contact 32 moves away from the contact 33 and the current circuit is broken. You achieve the same action if, during an electromagnetic shutdown, the core 44 with its grub screw 45 acts on the lower arm of the lever 41.
    The contact lever 24 after a short circuit under the influence of the lever 47 and through the zanlechik 46 core 44 very quickly tilts counterclockwise and due to this, the contact 32 moves away from the contact 33.
    As soon as the spring 28 is turned off, the contact holder 21 will turn through the latch 25, turning the contact holder 21 1) clockwise, the contact holder will grab the upper arm of the lever 41 and tilt it clockwise and, thus, the corresponding levers of both other single-pole overcurrent switches are captured by the connecting piece and the corresponding stop levers 16 tilt to the off position, causing these to turn off two single pole switches.
    If the control organ is firmly held in the direction of switching on, a free opening occurs, after which the single-pole switch takes the position shown in FIG. 3. With the free course of the governing body 1 he is already
    is turned off by the action of the spring 6 tilts towards the off position in a clockwise direction. A single pole switch locks in position (Fig. 2), in which the crank link is locked by the locking lever 16.
    Controls 1 cpsd of three single-pole switches are connected by external ends with two transverse switches.
    In the position of the three-pole switch of the maximum current shown on the fng. 2, external activation occurs, and the controls 1 should tilt clockwise (FIG. 2), in
    As a result, the cranked link of the contact carrier 21 straightened by the locking lever and the arm of the contact holder are rotated around the axis 22 in a clockwise direction. With this latch
    25 grips the contact holder 21, moves down (Fng. 2) and the spring 28 is tensioned. This movement continues until the protrusion 26 of the latch 25 contacts the fixed relative to the casing.
    stop 50. In this case, the contact 32 of the lever 24 is slightly higher than the contact 33, therefore, the switching position has not yet been made.
    The contact of the protrusion 26 of the latch 25
    with the stop 50, it will occur until the link formed by the arm 5 of the control unit 1 and stretched overnight in line and the locked link 16 crank link reaches its dead center.
    In order to reach the dead point with the crankshaft, the spring 10, the axis 8 of the lever 9, is compressed and becomes straight.
    This is in the groove 7 of the arm 5 in the direction to the axis 4 of the control body 1 moves
    axis 8. After the transition of the dead point, the protrusion 30 of the shoulder 5 of the orgap control 1 with the upper tail bar tilts the latch 25 counterclockwise so that its length 26 comes out of the engagement with the stop 50.
    Under the action of the tension spring 10, the cranked link of the contact holder 21 is locked and extended almost in line, and it touches the axis 22 and moves clockwise, resulting in a lever 24 with contact
    32 moves to copade 33 and instantaneous activation occurs.
