Ceramic Switch
The dual-control switch is a switch with two contacts: normally open and normally closed. Under normal circumstances, we use two dual-control switches to control a lamp or other electrical appliances. For example, when we go downstairs, we can turn on the switch, and when we go downstairs, we can turn off the switch. If you want to turn off the lights, you have to run a way to turn off the lights, which saves us a lot of things. At the same time, it is a very helpful tool for girls who are afraid of dark.
The application range of the single-lamp dual-control switch circuit is very wide. For the problem of how to connect the single-lamp dual-control switch, we can make an assumption. Assuming that the lighting lamp needs to be installed on the platform between the first floor and the second floor, then it needs to be on the first floor. Install a switch at the stairwell of the second floor, and then connect the power cord to the first floor.
