Abstract:
To prevent a key from left unextracted from a locked push button switch.SOLUTION: In a switch 1, when a push button 2 moves from a reference position to a push-in position on the rear side, a connection member 42 moves rearward from a first position, and is locked at a second position where the connection state with a terminal 43 is different from the first position. Subsequently, when a key 91 is inserted into a rotor 31 via a button key hole 211 and the rotor 31 is rotated, the push button 2 moves forward. The push button 2 is located at the reference position, and the position of the connection member 42 is sustained at the second position. When the key 91 is removed from the rotor 31, the connection member 42 is unlocked, and moves forward before being located at the first position. With such an arrangement, the key 91 can be prevented from being left unextracted from the switch 1.SELECTED DRAWING: Figure 1
