Switch device

Abstract

A switch device where the components include an actuator bar and a spring which can be installed one after the other from above through an upper opening of a casing, thereby enabling automation of a switch assembly operation. The casing, having a fixed contact, eccentrically supports a rockable conductor plate with a movable contact at one end. A switch operating member having an actuator element and an operating element is pivotally mounted in the casing. The actuator element has a vertical through-hole into which the actuator bar and spring are placed. The actuator bar extends out of the bottom end of the actuator element to contact the conductor plate. The operating element has a depending pressing projection formed on its bottom matching the location of the top of the through-hole into which the actuator bar and spring are placed. As the operating element and the actuator element of the switch operating member are assembled, the depending pressing projection of the operating element compresses the spring to press the actuator bar against the conductor plate. When the switch operating member is pivoted about its axis the actuator bar causes the conductor plate to rock, thereby causing the fixed and movable contacts move together or separate to effect a switching action.
