ABSTRACT:
A push-button switch for use in electronic devices is provided which reduces stress on contact parts. A C-shaped elastic member is secured at one end to a bottom wall of a switch casing and engages a movable member at its other end. The movable member in turn pivotably engages a contact member having movable elastic arms which abut non-conducting inclined surfaces on the bottom wall of the casing when the switch is open. To close the switch, a knob disposed slidably within the casing is depressed, bringing a bottom surface of the knob into engagement with an end of the movable member and deforming the C-shaped elastic member by bringing its ends closer together. Further, the contact member is caused to pivot about the movable member and move toward the bottom wall of the casing. Consequently, the movable elastic arms of the contact member slide off the inclined surfaces and into electrical contact with stationary contacts in the bottom wall of the switch casing to form a conductive path. The stresses incident to closing the switch are diffused by the C-shaped elastic member, reducing stress on the contact member and consequently reducing breakage of the contact member.
