Abstract
A toggle switch includes a toggle lever with a spherical portion that is held against a partially spherical surface by a retaining ring or a pin to permit the toggle lever to swivel. A coil spring coaxial with the toggle lever and enclosing a portion of the lever forces a plunger against an actuator that rocks to place a blade in contact with a terminal to operate the switch. Terminals are molded into the case of the switch to maintain the terminals in a desired position. The actuator may be shaped in one of several ways to provide maintained contact, momentary contact, or a combination of these. Electrical contacts are formed by placing spherical balls or similar shapes made of a contact material into holes in the terminals and then forming the balls or other shapes to produce a contact surface.
