Single live wire double-control switch wiring method and circuit

Abstract

The invention discloses a single live wire double-control switch wiring method and circuit, two same touch switches are selected, and a live wire of commercial power is connected with a first switch, a second switch, a load light and the first switch form a series connection and are connected with a neutral wire of the commercial power; each touch switch comprises a touch disc, an MCU and touch control circuit, a power supply voltage stabilizing circuit, a single live wire electricity acquiring module and a live wire electricity taking module, the MCU and touch control circuit is connected with the touch disc to serve as an operation mechanism, and a silicon controlled rectifier or a relay is adopted in the live wire control module to serve as a control mechanism. According to the invention, two same touch switches are serially connected with the load, only one wire is wired between the double-control switch, the structure is simple, the wiring is convenient, and the cost is lower than before; two switches are not major-minor switches, data transmission is not performed between the switches, the internal voltage variation can be detected only to judge if a user operates, and a purpose of open or close is achieved.

Description

technical field [0001] The invention relates to the technical field of lighting switch circuits, in particular to a double-control switch wiring method and circuit. Background technique [0002] Double control switches are used in many occasions, such as bedroom lighting and so on. The existing technology is to use the main switch in the dual control switch to control the on and off of the load. The main switch supplies power to the auxiliary switch through the two wires connected to the auxiliary switch, and at the same time transmits the data of the switch state, so as to achieve the purpose of controlling the lamps and lanterns. Purpose. Due to the division of main and auxiliary switches in such a solution, if damage occurs during subsequent use by the user, the user cannot determine which is damaged, and the two switches must be replaced together, which is costly and wasteful. Moreover, there are problems of code matching and circuit interference caused by communicatio...

AI Technical Summary

Problems solved by technology

Since such a scheme is divided into main and auxiliary switches, if damage occurs during subsequent use by the user, the user cannot determine which is damaged, and the two switches must be replaced together, which is costly and wasteful

And this way of the main and auxiliary switches has the problem of code matching and the circuit interference problem caused by the communication between the dual control switches.

In addition, most of the wiring schemes of existing double-control switches still have the disadvantage of being incompatible with the existing ordinary mechanical double-control switch circuits, and the switches of this circuit cannot be directly replaced and used, and can only be used after rewiring.
