CONSTITUTION: A tact switch is made up of connecting a case body 1a, a cover 1b and part of a tact button 2 solidly with a thin hinge part 6, and formed by simultaneous, integral working of those body 1a, cover 1b and button 2 through a plastic. Consequently, after a diaphragm movable contact 3 is parenthesized into the body 1a, the button 2 is rotated with the hinge part as a fulcrum, an engaging tappet 7 is engaged with an engaging recess 8, and both 1a, 1b are clamped to form a case 1, and simultaneously the tact switch is formed. At this time, since a top surface of a button part 2a of the button 2 is slightly projected outward from an inserting hole 5 of the cover 1b, the movable contact 3 comes into contact with a fixed contact 4 so that the switch is turned to ON. Next, when pushing pressure against the button 2 is released, the contact 3 restored to the original position so that the button 2 is also restored. According to this constitution, a process gets off with one time fabrication.
