ABSTRACT:
A push switch includes a housing having a top opening and a recessed section at a lower part, a push-type switch contact placed on an inner bottom face of the recessed section, an operating unit having an operating section at an upper part and a flange section at a lower part, a resilient unit placed under the operating unit in the recessed section for energizing the operating unit upward, and a cover for covering the top opening and having a center hole from which the operating section extends upward. The operating unit is movable vertically guided by a guide projection placed on inner walls confronting each other of the recessed section and extending vertically and by a concave section formed on the flange section for mating with the guide projection. The operating section includes faces vertically rising from the positions where the concave sections are recessed most inward.
