PURPOSE:To provide a push button switch of an elevator which can be simply made unable to operate in the condition of being once operated and can avoid misconception. CONSTITUTION:An opposed small holes 31 are provided on a button 2 and a button guide frame 3, and if necessary, a pin 4 is inserted into this hole 31 so as to restrain movement of the button 2. Hereby, when a unspecified floor not needed to stop is generated against an operating elevator, there is no necessity for customary change of a circuit on a large scale, and no misconception to be trouble against the invalid button. |
