Abstract
A snap-action overcenter contact mechanism utilizes a spring-loaded apexed plunger depressibly cammed within a rockable actuator block. The plunger rides in tracks in the block which ensure registered pivotal movement of the block and plunger, and also guides the plunger for depression within the block perpendicular to the pivotal axis thereof. A cam, which may be in the form of a roller mounted to a linearly sliding operator or a toggle lever operator, traverses the plunger to depress the plunger within the block against the bias of compression springs. When the cam translationally crosses the apex of the plunger, the stored energy of the springs is released, and the plunger and block pivot to an alternate position. A positive off feature is also disclosed wherein secondary cams formed on the operator strike the block to force it to pivot to an off position if the first cam has crossed the apex of the plunger and the block has not pivoted to the off position.
