ABSTRACT:
There is disclosed a multiple electrical contact switch which has a comb block whose teeth are inserted into receptacles of a mounting block thereby wedging pairs of electrical spring contacts, which are also inserted into the receptacles, between the teeth and the receptacles without bending the spring contacts. The electrical contacts extend from the receptacles and are activated by an operating card, which engages the extended portions of the electrical contacts to open or close electrical conduction paths. When pressure on the spring contacts from the actuating card is released, the spring contacts then move the operating card to an original position wherein the sequence of open and closed contact springs is as if there were no contact with the operating card and the contact springs.
