The switch actuating body 14 is made of a flexible elastic material and has a substantially convex cross-sectional shape by continuously forming stepwise shapes. an external protrusion (19 or 19') made of a flexible elastic material for making the buckling stress of the bulge stronger than the buckling stress of the first bulge, and the first bulge; A first movable contact 20 is disposed on the inner surface of the second movable contact 15, and a second movable contact 21 whose contact surface is located above the contact surface of the first movable contact 20 is disposed on the inner surface of the second bulge 17. arranged,
Further, on the insulating substrate 11 on which the switch actuating body 14 is placed, first and second movable contacts 20 and 21 are formed, which face each other in a non-contact state with the first and second movable contacts 20 and 21 due to the elastic force of the switch actuating body 14. 2 fixed contacts (1
2a, 12b and 13a, 13b), and a key knob 22 is placed so as to straddle the top of the second bulge 17 and the top of the external projection (19 or 19'). A multi-stage push button switch.
