ABSTRACT:
A center shaft (2a) for holding a key top (1), and springs (2b) are provided in a casing (2) of a small-sized electronic equipment such as an inter-call receiver. The springs (2b) are provided so as to extend from the peripheral portions toward the center shaft (2a), and holes are formed in the springs (2b) respectively. The key top (1) is provided with a stopper nail (1a), first protrusions 1b and second protrusions 1c. The protrusions (1c) of the key top (1) for pushing switches (3) are inserted through the holes of the springs (2b) respectively, and the stopper nail (1a) of the key top (1) is engaged with the center shaft (2a) acting as a fulcrum during the seesawing operation of the key top (1). Thus, the key top (1) is held in a stable manner. The existence of the center shaft (2a) prevents simultaneous depression of the two switches (3).
