ABSTRACT:
A switch case 10 is provided with a heart-shaped cam groove member 15 having a cam groove 16 and there is inserted a return spring between the switch case 10 and a contact holder 30. The contact holder 30 is provided with a lock pin 60 having the top end 64 thereof engaged with the cam groove 16. The lock pin 60 has a curved portion 61 adapted to be pressed by a portion of a contact plate 50, wherein the top end 64 of the curved portion 61 is held into engagement with the cam groove 16. As a result, an extra space for the cam groove, 16 is not needed any more on the side of the contact holder 30, contributing to miniaturization of the whole switch assembly. Further since the lock pin 60 is pressed by means of the contact plate 50, it is unnecessary to have an exclusive return spring provided therein.
