Problems solved by technology

[0002] In the prior art, if it is necessary to realize multi-point control of an electrical appliance, it is necessary to use a special multi-connector switch to realize it through power line wiring.
At present, most of them use double-connected switches. If three or more positions are required to control an electrical appliance, it is difficult to use ordinary double-connected switches, and ordinary electricians will not install them.

Abstract

The invention discloses a multi-point control switch, which comprises the following parts: binding post J1 and J2, main switch Kz and multi-auxiliary switch Kf, load resistance R1, R2 and R7, bias resistance R3, R4 and R6, charge-discharge current-limiting resistance R5, voltage-limiting current-limiting resistance R8, charging capacitance C2, filter capacitance C1, by-pass capacitance C3, C4 and C5, triode T1, T2 and T3, single-direction controllable silicon T4, commutating bridge Q, diode D1 and D2. The main switch parallels the auxiliary switch with random switch controlling the path and discontinuity of main circuit.

Description

technical field [0001] The invention relates to an electronic switch, in particular to a multi-point control switch. Background technique [0002] In the prior art, if it is necessary to realize multi-point control of an electrical appliance, it needs to use a special multi-connector switch to realize it through power line wiring. The wiring is relatively complicated, and it needs to be connected by multi-wire, so it is difficult to realize. At present, double switches are mostly used. If three or more positions are required to control an electrical appliance, it is difficult to implement with ordinary double switches, and ordinary electricians will not install them. Contents of the invention [0003] The object of the present invention is to provide a light touch switch capable of realizing multi-point control aiming at the deficiencies of the prior art. [0004] The present invention includes two terminals J1 and J2, main switch Kz and multiple auxiliary switches Kf, lo...
