Provided is a push switch including: a tubular case; a slider which is supported by the tubular case to reciprocate and advance during a pushing operation; and biasing means for biasing the slider to retreat, wherein the slider upon retreating is automatically returned to a non-operation position by allowing a contact inclined surface provided at a contact portion of the slider to come in contact with a restriction inclined surface provided at a restriction portion of the tubular case, the slider is a mold made of a resin material having a higher thermal contraction coefficient and a lower melting temperature than those of the resin material of the tubular case, the shape of the contact portion is similar to and slightly smaller than the shape of the restriction portion in order that they be complementary to each other, and the tubular case is provided with a pair of restriction inclined surfaces.
