Description

(54) SWITCH

The invention relates to radio engineering and can be used in switching installations for various purposes. According to the main author. St. No. 645286 is known for a switch comprising remote switches, control buttons, a key executed on a transistor, a resistor 1. However, a known switch consumes a significant amount of electrostimulars. The purpose of the invention is to reduce the consumption of electricity. For this reason, in the switch in series with the windings of the remote switch disconnecting contacts are connected, and capacitors are connected in parallel with the windings of the remote switch disconnectors. The drawing shows a structural electrical diagram of the proposed switch. The device contains control buttons 1-3, remote switches 4-6 with write windings and tapping 7 and 8, power bus terminals 9 switch, made on transistor 10, resistor 11, closing contacts 12 and capacitors 1 The device operates as follows. Let the remote switch 4 be in the operating state at the time in question. Its closure contacts 12 are closed, and the closure contacts 12 of the other remote switches 5 and 6 open. When you press any button, for example 2, the current flows through the winding of the recording 7 of the remote switch 5, which, having triggered, closes its closing contacts 12. But due to the current flowing through its recording winding 7, the transistor 10 opens, which together with the closing contact 12 the remote switch 4 forms a current circuit which, having charged the capacitor 13, flows through the winding of the 8 of the remote switch 4. The latter is triggered and returns to its original state, breaking with its make contacts 12, the circuit of its own winding is disconnected 8. The discharge of the capacitor 13 through the disconnect condition 8 of the remote switch 4 ensures its reliable operation.

In order to accomplish the required switching, the current flows through the recording windings and outlets 7 and 8 of only those two remote switches, for example 4 and 5, which are needed. the change in position, and the amount of current consumed by the device when switching, is reduced. Moreover, the current across the winding from the return to the initial position of the distant switch 4 proceeds only during the really necessary time, and not all the time while the control button 1 is pressed.

In the proposed device, both the switching current strength and its duration, i.e. reduced power consumption.
