Switch arms connected to external circuits in a portable unit have a conductive contact area for selectively engaging the contact strips, thereby connecting the base unit and portable unit. A cover on the connector body rotates under pressure from the switch arm to direct excess force from the switch arm around the connector. The range of rotation of the cover is limited under contact of a plurality of stoppers by contact between the cover and a fixed plate. In this manner, excess force from the switch arm is never applies directly to the connector body or underlying connections.
