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.

Rocker switch

A socket connector which can accommodate a first plug connector or a second plug connector has a cylindrical cavity with a first plurality of socket contacts and a second plurality of socket contacts. The second plurality of socket contacts are shorter than the first plurality of socket contacts. The first plug connector has a number of plug contacts arranged for mating engagement with both the first plurality of socket contacts and the second plurality of socket contacts. The second plug connector contains a number of plug contacts arranged only for mating engagement with the first plurality of socket contacts. The socket connector is constructed and arranged so as to allow penetrating travel of the first plug connector fully into the cylindrical cavity so as to engage with the plug contacts the first plurality of socket contacts and the second plurality of socket contacts while limiting penetrating travel of the second plug connector into the cylindrical cavity to a point at which the plug contacts engage the first plurality of socket contacts but the second plurality of socket contacts are neither engaged nor contacted by the second plug connector.
