SWITCH WITH RESETTING MECHANISM

PROBLEM TO BE SOLVED: To enhance the stability and reliability of control and achieve miniaturization. SOLUTION: This switch includes a control button biasing part 7 having a return spring 25 which biases a control button 3 in the clockwise direction and a resetting mechanism 8 which, when the control button is rotated counterclockwise, holds the return spring 25 of the part 7 compressed to lock the sliding element 16 of the part 7. The resetting mechanism 8 comprises a fitting element 17 which is fitted into the sliding element 16 of the part 7 when the return spring 25 of the part 7 is compressed, a spring 18 biasing the fitting element 17 toward the part 7, and a solenoid 19 secured to the fitting element 17 via the spring 18. The solenoid 19 has a movable core 20, a coil 21 wound on the movable core 20, and a fixed core 22 secured to one end of the coil 21, and releases the fitting element 17 from the state of being fitted in the sliding element 16 of the part 7 by moving the movable core 20 toward the fixed core against the biasing force of the spring 18, by means of a magnetic field produced by passing electricity to the coil 21. Thereby the control bottom 3 is reset.
