ABSTRACT:
A thimble-shaped button actuator largely formed of insulating material has a cup-like base with an inside step and is symmetrical about an axis. A thimble is reciprocable in the base along the axis. A spring is seated against the closed end of the base and the closed end of the thimble and urges the thimble in a direction away from the base and against a snap ring in the base in the path of a flange on the thimble. An electrically conducting ring on the thimble is moved by axial pressure on the thimble to abut a pair of electrical conductors seated in the base and overlying the step. Electrically conducting binding screws are recessed in and pass into the base to engage threads in the conductors.
