Single-link dual-control switch wiring method
Connect the two contacts of the two single-pole, double-throw switches, ie, contact 1 of switch 1 is connected to contact 1 of switch 2, contact 2 of switch 1 is connected to contact 2 of switch 2, and then 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.

1, see the appearance
Good quality single-link dual-control switch, the appearance of smooth and smooth appearance, no glitches, most will choose ABS + PC material, strong and unbreakable texture, but also has a flame-retardant performance!
2, measured stability
The installation and dismantling of the single-gang dual-control switch with good quality requires special tools. In the optional switch, you can use the index finger and thumb respectively according to the diagonal cover, one end is pressed, one end of the force to the following pressure, if the cover is loose and loose, then the switch quality is relatively poor;
3, test button
The single-unit dual-control switch button has two structures: a plate-sliding type and a pendulum-type type. Good quality rocker-type keys sound crisp, with metal impact sounds, while board-sliding sounds are slight and feel smooth. If the sound during the trial is not pure, dynamic and stagnant, there is an intermittent state, indicating that the quality of the single-link dual control switch is poor!
Editor's summary: About what is the connection method of single-link dual-control switch and single-link dual-control switch, it is introduced here, and we hope to help everyone. Want to learn more related knowledge can focus on this site information.
