Dual control switch wiring method comprehensive analysis
Because there are many kinds of dual-control switches, many consumers often confused the dual-control switch wiring method because they are not professional. Today, with a small series to see the dual control switch wiring method a comprehensive analysis, for your reference oh.
Dual control switch wiring method - single dual control
Connect the two contacts of the two single-pole double-throw switches, ie, the contact 1 of the switch 1 is connected with the contact 1 of the switch 2, the contact 2 of the switch 1 is connected with the contact 2 of the switch 2, and then the two switches The knife is used to connect the two ends of the lamp to both ends of the entire switch. In this way, when the switches of the switches 1 and 2 are simultaneously connected to the respective contacts 1 or simultaneously to the contacts 2, the circuit is switched on and the lamps are lit. If one of the two switch blades strikes contact 1 and the other strikes contact 2, the circuit fails and the light goes off. Therefore, both switches can control the lamp. The two switches can be placed at the upper and lower ends of the stairs or at both ends of the corridor so that the lights can be turned on before entering the hallway, and the lights can be turned off at the other end after passing through the corridor. This can both illuminate and prevent people from losing the lights. Electricity.
Dual control switch wiring method - dual dual control
First connect the middle terminal of a dual-control switch to the live wire, and then connect the middle terminal of the other dual-control switch to the lamp cap (or the center tongue of the screw base), and then connect the return line, that is, use two green lines. Wires connect any of the two upper and lower terminals; the wire is directly connected to the other contact of the lamp (or the thread of the screw base). This completes the connection.
Dual control switch wiring method - triple control
The triple light switch L (incoming line) is connected with a wire and the fire wire in the switch box is connected. The remaining three wires in the switch box are connected to L11 (also can be connected to L12).
When L is connected to the live line, only one circuit (L1) output is available for the single-link switch, and two (L1, L2) outputs are provided for the dual switch. The triple switch has three (L1, L2, and L3) outputs. The communication bus crystal head is required to access COM1. When other intelligent products are installed adjacently, it can be connected to the COM1 interface of the adjacent smart product through the bus expansion interface COM2. If the optional intelligent switch specification indicates that COM2 is a sensor interface (ie, 6P4C interface), it cannot be used as a communication bus expansion interface.
The relevant information about the wiring method of the dual control switch is introduced here for everyone. I hope this article will be helpful to everyone.
