ABSTRACT:
A "hi/lo" headlight beam selector switch system having a "flash-to-pass" mode, including a terminal block having a back panel with a set of profiled terminal pads mounted thereon, at least one, linearly movable carrier having on its side facing the pads at least one contactor having multiple contact dimples thereon, the dimples being drawn linearly across the back panel interconnecting two or more pads as the carrier(s) move(s) along side them. In a first embodiment (FIGS. 1-3B) two separable carriers, the lower, "hi beam" one of which can be latched down in place, have two return springs, a weaker one positioned between them and a stronger one under the bottom of the "hi beam" carrier; while in a second embodiment (FIGS. 4 & 5) a single carrier working with only three terminal pads compared with four pads is used. In the first downward movement of the carrier(s) the "flash-to-pass" circuit is closed, while maintaining the "lo" beams "on;" while, if a further linear movement is used, the lower or sole carrier is latched in place, selecting and maintaining the "hi" beams "on." Repeating the maximum linear movement unlatches the carrier, returning the selector switch to its "lo" beam mode. The latching and unlatching is achieved with the use of a detent spring having a projecting tip, which engages and co-acts with an asymmetrical "heart shaped" cam.
