Abstract
A switch, especially for heavy duty vehicle applications, utilizes solid state circuitry and a low voltage, low current touch pad switch, where the switching occurs directly on a printed circuit board and bulky wire terminations are eliminated. The switch includes a rocker, which pivots at its center point fulcrum causing the switch lever, housed inside the switch and attached to the rocker, to move in a particular direction. The configuration of the lever is such that the extending ears on opposite sides press against the elastomer seal and move a carbon contact against the integrated circuit traces on a printed circuit board, completing an electrical circuit. This condition occurs for either directional movement of the rocker. Housed within the lever is a spring-loaded plunger fitted with a roller (wheel) at its end. The roller rests on a predesigned detented ramp located as an integral part of the switch insulator.
