Claims

[Scope of utility model registration request]

A tact switch mounted on a board, and a boss portion that is arranged to be movable in the vertical direction and protrude downward in an area above the tact switch on a panel surface arranged above the board. includes a key top extending to the vicinity of the switch stem on the upper surface of the tact switch, and a support member fixedly disposed with respect to the substrate, the support members being distributed around the key top, and It is connected to the sides of the key top via a plurality of resilient hinges formed to extend substantially circumferentially of the key top, and typically the hinges of the support member push the key top upwardly.
A switch mechanism characterized in that when the upper surface of the key top is pressed down, the lower end of the boss portion of the key top pushes the upper end of the switch stem of the tact switch downward, thereby performing a desired switching action.
