Push switch device

A push switch device including a housing, first and second terminals having connection pieces disposed on a bottom surface in the housing, and a dome-shaped movable terminal installed in the housing and having an apex pressed to be resiliently deformed and recovered to electrically connect or open the connection pieces of the first and second terminals, which comprises:

• a first pressing member having a pressing projection disposed over the movable terminal to contact the apex of the movable terminal and installed in the housing to press the apex of the movable terminal downward to resiliently deform the movable terminal and be rotated about a switching direction;
• a second pressing member installed in the housing to overlap the first pressing member to be rotated about the same rotational center axis as the first pressing member;
• a push button passing through one sidewall of the housing to be partially exposed to the exterior and moving straightly in a push direction perpendicular to the switching direction of the movable terminal to relatively rotate the first and second pressing members in opposite directions;
• and
• a push direction conversion unit installed at the first and second pressing members and converting the relative rotation of the first and second pressing members into a push movement in the switching direction in which the pressing projection of the first pressing member presses the apex of the movable terminal downward.
