ABSTRACT:
The clip-mount operates with a button sub-mount system and includes a body defining a locking cavity for the button and a resilient locking tongue therein. The tongue biases the button into a locking position with a cam surface. A movable cam actuator on the body includes another cam surface which coacts with the first cam permitting the tongue to flex or unlock. The actuator is a two piece actuator with one member-cam surface made of harder, polycarbonate plastic resin than the other and the tongue cam surface. An enhancement includes both an unlocking cam and a second locking cam structure. The method includes biasing the button to a locking position and moving one cam over another thereby flexing the tongue from a locked to a button release position. A plastic spring biases the actuator-plunger.
