A push-type electric device includes a case having an opening defined in a top wall thereof, and a control member slidably disposed in the case and movable therein for actuating the push-type electric device. The control member has a head projectable through the opening. The case has opposite side walls each having in an inner surface thereof a pair of slide guide grooves spaced from each other. The control member has opposite side walls each having on an outer surface thereof a pair of ridges spaced from each other and loosely fitted respectively in the slide guide grooves. Guide means are mounted on each of the ridges and extending in a direction normal to the direction in which the control member is movable in the case, the guide means being engageable with the side wall surfaces when the control member is tilted in the case.
