ABSTRACT:
A momentary contact switch is comprised of an insulator base member having a plurality of aligned dome shaped contacts extending upwardly from the top face. First and second pairs of notches or voids extend through the base member beyond opposite ends of the aligned stationary contacts. An elongated plastic actuator is disposed above the stationary contacts and extends both transversely and longitudinally beyond the aligned contacts. The actuator has four yieldable legs at or adjacent its four corners which extend downwardly and each leg is inserted through a respective notch. One pair of legs is shorter than the other pair. Each leg has a barb or wedge shaped element at its bottom for releasably engaging the under side of the base member to maintain the actuator and base member in operative relationship. A movable spring contact member is disposed between the base member and actuator. The spring contact member is an elongated strip of thin, yieldable, conductive material that has a reverse bend intermediate its two ends to form long and short legs. The short leg has a seat or pocket formed therein which fits over and in contact with an end one of the stationary contacts. The reverse bend of the spring contact member is located closer to the pair of short legs of the actuator.
