Abstract
A push switch device of the invention comprises a body including a set of terminals and closed via a cover. An inner side of the cover is provided with a second resilient unit on which is formed a stopper portion. A push unit is further formed through the body, the push unit being provided with a stop controller pad made of an abrasion-resistant material that is vis-a-vis the stopper portion. A first resilient unit is further placed below the push unit. With the above disposition, when a pressure is exerted on the push unit, the stop controller pad pushes on the stopper portion that moves outwardly. Thereby damage due to wear of the push unit is prevented.
