To provide a reverse spring for a switch capable of holding a pressure transmitting member on a spring member with a strong holding force, and to provide a switch device having the reverse spring for switch.

The reverse spring 6 for the switch includes a spring member 6a which is reversed when receiving a pressing force by an operating part 7 and self-restorable when the pressing force is released, and the pressure transmitting means that is a protrusion 6b to transmit the pressing force from outside to this spring member 6a, and the spring member 6a has a coupling part 6a4 to integrally couple and hold this spring member 6a and the protrusion 6b. Moreover, the spring member 6a consists of a movable contact having contact parts 6a1, 6a2, 6a3, and the protrusion 6b consists of a synthetic resin. The coupling part 6a4 of the spring member is formed to be embedded in this protrusion 6b.
