(54) SWITCH

The invention is intended for switching electrical and radio circuits and can be used in various devices of measuring and radio equipment.

The switches on the rotary-type reed switches, containing reed switches located around the circumference of the cylinder and located inside, are widely known. The mechanism for moving the control permanent magnet [1].

The disadvantages of such switches are that the control permanent magnet must be moved around the circumference and the operation of unnecessary reed switches increases the “knowledge of the switch.

, This disadvantage is eliminated in the switch containing the housing, reed switches located in the housing along the radii of a circle at the same distance from its center, a movement mechanism made in the form of a pivot arm with a pin on one end and a control permanent magnet mounted on the other end of pivot arm [2].

This switch has the disadvantage that switching and fixing the movement mechanism is carried out mechanically using a spring, which increases the wear of the switch and reduces its service life,

The purpose of the invention is to increase reliability.

This goal is achieved by the fact that in the switch containing the core, reed switches located in the housing, along the radii of the circle at the same distance from its center, a movement mechanism made in the form of a pivot arm with a pin on one pin and a control permanent magnet mounted on the other end of the pivot arm, another permanent magnet is inserted, installed in the housing 'outside the action of the reed contacts, so 2θ that its magnetization axis coincides with the magnetization axis of the control permanent magnet, and their different The named poles are directed towards each other, and reed switches equipped with pole tips are used in the switch25.

Figure 1 shows a switch, a General view; figure 2 is a section along aa in figure 1. An example is a switch with three reed switches.

J with another permanent magnet coaxial to the middle reed switch.

The switch consists of a housing 1, in which the reed switches 2,3 and 4 are installed. The control permanent magnet 5 is fixed on the end of the lever 6 having a pin 7, the other permanent magnet 8 is mounted coaxially with the reed switch 3. Pole tips are installed on the reed switches 2,3 and 4, 9.

The switch operates as follows.

In the central position, the lever 6 of the control mechanism of the control permanent magnet 5 is held above the reed switch 3 with the help of another permanent magnet 8 and closes the contacts of the reed switch 3. When the lever is moved to the right or left, the contacts of the reed switch 3 open and the contacts of the reed switch 2 or 4 are closed, respectively. The lever 6 is fixed for the reed switch 2 and 4 by means of the interaction of the control permanent magnet 5 with the pole tips 9 of the reed switch 2 and 4..

In the proposed design of the switch, mechanical locking of the lever by means of a spring is excluded, which reduces the switching force, reduces wear and increases the service life of the switch. 3Q The introduction of pole pieces allows you to fix the lever on the reed switches and at the same time increases the reliability of their operation.

Claims (2)

The invention is intended for the commutation of electrical and radio engineering circuits and can be used in various measuring and radio equipment. Switches on rotary type reed switches, containing reed switches located around a cylinder and located inside a mechanism for moving a control permanent magnet 1, are widely known. The disadvantages of such switches are that the control permanent magnet needs to be moved around a circle and the operation of unnecessary Reed switches increases the -wear switch. This disadvantage is eliminated in the switch containing the case, the reed switches located in the case along the circumference of the circle at the same distance from its center, the movement mechanism, made in the form of a pivoting lever with a pin at one end and controlling a permanent magnet. the other end of the pivot arm 2. This switch has the disadvantage that the switching and fixing of the moving mechanism is performed mechanically by means of a spring, which increases the wear of the switch and reduces its lifespan office workers The purpose of the invention is to increase the reliability of work. The goal is achieved by the fact that, in a switch comprising a housing, reed switches located in the housing, along the radii of a circle at the same distance from its center, the movement mechanism is made in the form of a rotary lever with a pin on the same end and a control magnet mounted on the other end of the pivot arm, another permanent magnet is inserted, mounted in the housing outside the zone of action on the reed switches, so that its axis of magnetization coincides in the axis of magnetization of the control magnet, and their differences ennye poles directed towards each other, wherein a reed switch is used, equipped with pole shoes, Figure 1 illustrates a switch, general view; figure 2 is a section along aA. On figure 1. As an example, a switch with three reed switches is shown. another permanent magnet mounted coaxially to the middle reed switch. The switch consists of case 1, in which the reed switches 2,3 and 4 are installed, the Controller permanent magician 5 is fixed at the end of the lever b, having a trunnion 7, another permanent magnet 8 is installed coaxially with the reed switch 3. On the reed switches 2,3 and 4 are installed pole pieces, 9. The switch operates as follows. In the central position, the lever b of the mechanism for moving the control permanent magnet 5 is held over the reed switch 3 by means of another permanent magnet 8 and closes the contacts of the reed switch 3. When the lever is moved to the right or left, the contacts of the reed switch 3 or closure of the contacts of the reed switch 2 or 4 respectively occur . The lever 6 at the reed switch 2 and 4 is fixed using the interaction of the control constant magnet 5 with the pole tips 9 of the reed switches 2 and 4.. In the proposed design, the lever is prevented from mechanically locking the lever using a spring, which reduces the switching force, reduces wear and increases the service life of the switch. The introduction of pole lugs makes it possible to fix the lever at reed switches / J / J, L and at the same time increases the reliability of their operation. The invention includes a switch comprising a housing, reed switches located in the housing along the radii of a circle at the same distance from its center, a movement mechanism made in the form of a pivot arm with a trunnion at one end and a control permanent magnet mounted at the other end of the pivot arm , characterized in that, in order to increase the reliability of operation, another permanent magnet is inserted into the switch, which is installed in the housing outside the zone of action on the reed switches, so that its axis of magnetization coincides with the axis of the magnetizing the vanes of the control permanent magnet, and their opposite poles are directed towards each other, with reed switches with pole tips used in the switch.
