Abstract
A switch actuator providing a floating operating and release point switch including a base, a plunger having an exposed operating end mounted for movement on the base, a mount for relatively movable switch contacts on the base, and a friction piece normally grasping the plunger so as to be movable therewith and yet be relatively movable with respect to the plunger when movement of the friction piece is resisted. The friction piece is oriented with respect to the mount such that movement of the friction piece may effect relative movement between relatively movable switch contacts mounted to the base.
