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.

Embodiment Construction

[0022] In this example, refer to figure 1 and figure 2 , the single live wire double control switch wiring method, select two identical touch switches, connect the live wire of the mains to the first switch, the second switch and the load lamp form a series connection with the first switch, and then connect them together Connect to the neutral line of the mains;

[0023]The touch switch includes a touch panel, an MCU and a touch control circuit, a power supply voltage stabilization circuit, a single live wire power-taking module and a live wire control module, the MCU and the touch control circuit are connected to the touch panel as an operating mechanism, and the power supply voltage stabilization circuit is connected to the MCU and the touch The control circuit forms a DC stabilized voltage output and DC low voltage detection input circuit. The single live wire power supply module is connected to the power supply voltage stabilizer circuit to form a DC low voltage output a...

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...
