Abstract
A movable contact assembly comprises a movable contact arm carrying a movable contact element, an electrically insulating contact holder for holding the movable contact arm and movable between the open and closed positions, a compression spring for resiliently holding the movable contact arm relative to the contact holder, and a spring retainer disposed between the compression spring and the movable contact arm. The spring retainer has first and second sloped guiding surfaces. The movable contact arm has first and second sloped guided surfaces thereon. The sloped guide surfaces of the spring retainer serve to guide, in cooperation with the sloped guided surfaces of the movable contact arm, the movable contact arm into a predetermined proper positional relationship relative to the movable contact holder due to the spring force of the compression spring.
