PROBLEM TO BE SOLVED: To provide a push-button switch with small size, good operability, and few solder peel-off. SOLUTION: On the push-button switch, recess and projection parts 1h, 6g are arranged between a front surface 1a of a housing 1 and a front panel 6b of a cover 6. When the front surface 1a side of the housing 1 moves upward so as to separate from a printed circuit board 8, since the upward movement of the housing 1 is prevented by the recess and projection parts 1h, 6g, and the recess and projection parts 1h, 6g are in the relation of engaging with each other, the upward movement of the front surface 1a as a moving side is small. By the above, the operability is good, and since the upward movement of the front surface 1a is a repetition of a small movement, the peel-off of the solder 9 between a terminal part 2c and the printed circuit board 8 becomes few.
