(under subclass 185) Subject matter wherein the significant actuating structure includes means whereby the contact motion is caused to take place abruptly and is not dependent on the rate of movement of the armature. The contact movement is usually accomplished by a spring connection between the operator and the contact in such a manner that the initial movement of the armature or other actuating means places the spring under tension until released whereupon the movable contact is snapped to open or closed position by the energy stored in the spring.
