To provide a push-on switch easily manufactured, capable of reduction in size, and in which a movable contact member can be firmly fixed to a switch body.

A movable contact member 5, including a tactile conductive plate 33 and a pair of electrode forming members 35, is arranged on a switch body 1. A conductive plate-receiving rising wall 39 provided integrally with the switch body 1 is thermally deformed toward the tactile conductive plate 33 to construct a conductive plate movement-prevention structure for preventing movement of the tactile conductive plate 33 relative to the switch body 1. An electrode forming member-receiving rising wall 47 provided integrally with the switch body 1 is thermally deformed toward the electrode forming member 35 to construct an electrode-forming member movement-prevention structure for preventing movement of the electrode forming member 35 relative to the switch body 1.
