PROBLEM TO BE SOLVED: To provide a switch mechanism allowing operation force of a push-button switch to be easily selected. SOLUTION: This switch mechanism is so structured that a movable contact 9 is pivotally supported to a rising piece 13a of a common terminal 13 arranged on a base body 8; a pulling spring 10 is connected between an operation piece 11 arranged at a position facing to the movable contact 9 by interposing the rising piece 13a and the movable contact 9; thereby a contact mechanism part is formed; and operation force can be selected by pressing it by a pressing part 3e formed on a plunger 3 through a pressing piece 7 movable between the upper side of the operation piece 11 and the upper side of the pulling spring 10.
