The exhaust fan switch in the kitchen of the rented house is broken, and I want to modify it myself

There are three wires on the switch, one is the live wire, and the other two are to control the rotation of the motor, one of which is to turn to the left, and the other is to turn to the right, (cut off the power supply first, unplug the plug) directly cut the wire from the root of the switch with scissors, (Note: if the negative wire is also passed from the switch, the negative pole of the power supply and the negative pole of the motor are directly connected, and they are tightly wound with insulating tape) The positive wire of the power supply is connected below, (pull the fan apart) connect the positive wire of the plug with any of the wires, and screw the wires together, Then plug in the plug (be careful not to be electrocuted) The fan turns, look at the direction it turns, whether it is to suck the air indoors, or to blow the air outdoors, whether to blow the wind directly and cut off the power supply and tighten the wire to wrap the insulating tape, if it is not to blow the wind and change to another line. This way, your fan will only have to blow air outward, because there is no transfer switch, and you can't suck in as much air as you used to.

The cable is still the original cable, which can be turned off and turned on without impact, but the switch cannot be used, and the plug can only be pulled out to turn off the power.

You're a woman, if you're a man, change it yourself. Otherwise, how to be in charge?

Because the kitchen is heavier, the oil is heavier, I suggest, good size, buy a simple exhaust on the Internet and replace it, this is the most trouble-free!
