Abstract

A spring for a switch actuating assembly is of generally E-shape or sinuous configuration wherein inwardly-curved free ends of outer sections are adapted to engage the legs of a central U-shape section when the spring member is compressed, thereby limiting the movement of the outer sections and increasing the spring characteristics of the spring member. The spring can be disposed in a slide member in a housing and be movable from one selected position to another so that the spring moves a movable contact member from an electrically connected condition to a disconnected condition.
