Abstract
A push switch contains a case including a housing space having an upper-opening and including fixed-contacts disposed on a bottom of the housing space, a movable contact member disposed in the housing space configured to deform in response to receiving pressure applied from above, and contacting the fixed-contacts upon defoming in response to the received pressure, and a pushing member disposed on the movable contact member and configured to transmit the received pressure to the movable contact member. The movable contact member includes a pair of first-linear edges, wherein the pushing member includes a plurality of projecting-pressing portions disposed on a bottom surface of the pushing member facing the movable contact member, and wherein the plurality of pressing portions is disposed on the bottom surface at positions not overlapping a straight-line that passes through a center of the movable contact member and intersecting each of the pair of first-linear edges.
