Problems solved by technology
[0002] The door control switch is a switch that can turn on the light by opening the door. After entering, the light is still on when the door is closed, and the light is off when the door is closed again. The bathroom is a place that must be visited every day. It is very troublesome to turn on and off the light when entering the bathroom at night. If you forget to turn off the light, it will cause a waste of electric energy. The door control switch of the traditional bathroom light is unstable, and the light is prone to suddenly go out.

The invention discloses a gate controlled switch used for toilet lamps. The switch comprises an alternating current power supply, first to fourth capacitors, a voltage-stabilizing diode, a diode, first to seventh resistors, a normally-opened reed pipe, a first double D trigger, a second double D trigger, a bidirectional silicon controlled rectifier, a switch pipe and a bulb. The first double D trigger, the third capacitor, the third resistor and the fourth resistor form a monostable circuit. The second double D trigger, the fourth capacitor, the fifth resistor, the sixth resistor and the seventh resistor form a bistable circuit. The monostable circuit and the bistable circuit form a switch memory circuit. On and off of the lamps are controlled via the output of the first double D trigger. In this way, the gate controlled switch works stably.
Description
technical field [0001] The invention relates to a door control switch, in particular to a door control switch used for bathroom lights. Background technique [0002] The door control switch is a switch that can turn on the light by opening the door. After entering, the light is still on when the door is closed, and the light is off when the door is closed again. The bathroom is a place that must be visited every day. It is very troublesome to turn on and off the light when entering the bathroom at night. If you forget to turn off the light, it will cause a waste of electric energy. The door control switch of the traditional bathroom light is unstable, and the light is prone to suddenly go out. Contents of the invention [0003] The object of the present invention is to provide a door control switch for bathroom lights in order to solve the above problems. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [000...
