Mirror control switch for automotive vehicles

Abstract

The disclosed mirror control switch comprises a cluster of four push buttons for operating a cluster of four push button switches, each of which is a single pole double throw switch for energizing UP-DOWN and RIGHT-LEFT mirror adjusting motors in either of two directions. A slide action selector switch is also provided for switching the connections of the push button switches between left and right mirror motors. Each push button switch comprises a contactor which is slidable between first and second fixed contacts adapted to be connected to a pair of battery terminals. An insulating member is provided between the contacts to prevent the contactor from bridging between the contacts, so that the contactor provides a break-before-make switching action to obviate any possibility of short circuiting the battery. The contactor is generally U-shaped and has a first spring arm for engaging the first and second fixed contacts and a second spring arm for slidably engaging an additional fixed contact which is connected to the selector switch and to the output terminals to which the motors are connected. The selector switch has first and second contactors, each of which is engageable with three successive fixed contact elements to provide a double pole double throw switching action. The first and second contactors are mounted on a carriage which is slidably guided by a rib having a T-shaped cross section.
