In this example, only one case 23 is inserted into the opening of the switch panel 1 from above, and is fixed using a washer 24 later. This case 23 forms, on the one hand, a guide for the push rod 25 and, on the other hand, has a contact 26. This contact member 26 comprises a contact sliding portion 27 forming an operation extension 28 above. The spring 29 pushes the contact slide 27 upward, and presses the operating extension 28 of the contact member 26 against the front end face of the push rod 25. The two contact springs 30 connected as a contact bridge 31 are in contact with the outer peripheral surface of the contact slide portion 27 made of an insulating material. In the case of this control switch, if the case is damaged and the push rod 25 falls down, the spring 29 pushes the contact sliding portion 27 upward in the operating state. When the push rod 25 is pushed, the contact slide 27 is pushed against the spring 29, so that the electric circuit is also interrupted.
