Abstract
A snap-action switch is disclosed which includes a movable contact carried by an over-the-center toggle-like spring armature to snap between a first position and a second position. The armature is moved by a pushing member which, in turn, is moved by a switch activator. An energy absorbing spring member is disposed between the switch activator and the pushing member. The spring absorbs forces at least equal to the force necessary to initially move the armature in a direction from its first position to its second position. When the force necessary to move the armature becomes less than the forces absorbed by the spring, the absorbed forces are released to move the armature quickly through its deadband zone and snap the armature contact to its second position.
