The circuit is simple, easy to make without debugging, and it can be used for bathroom exhaust fan controlling. The bathroom door controlled switch circuit consists of power circuit and control circuit, and it is shown in the figure. R selects 1/4W carbon film resistor or metal film resistor.C1 and C2 select aluminum electrolytic capacitors with voltage in 16V.VD uses 1N4001 or 1N4007 silicon rectifier diodes.UR selects 1A , 50V rectifier bridge pile.V uses C8050, S8050 or 3DG8050 silicon NPN transistor.T chooses 3W power transformer with 9V secondary voltage.K selects 4098 9V DC relay.S1 is theoriginal ventilator outlet's power switch; S2is broken (normally closed ) micro switch or button.
