Abstract
The disclosed pushbutton operated automotive air control unit incorporates a non-latching pushbutton switch for causing momentary switching of a control circuit, such switch being pre-assembled as a cartridge for easy insertion into the housing of the control unit. The switch comprises a pushbutton member which is telescopically engaged with a body member for sliding movement of the pushbutton member between extended and depressed positions. A return spring is interposed between the pushbutton member and the body member. The pushbutton member has a rearwardly projecting finger affording a switch carriage, slidably received in a guide channel in the body member. An electrically conductive contactor is mounted on the carriage and is selectively engageable with first and second fixed contacts mounted on the body member along such channel. The contacts are connected to first and second terminals which project rearwardly from the body member and are adapted to be inserted into slots formed in the rear wall of the housing for the air control unit. The housing has a front panel with an opening therein for slidably receiving and retaining the pushbutton member. Detents are formed on the pu…
