PROBLEM TO BE SOLVED: To provide a switch capable of ensuring longer life at reduced cost on a returning spring. SOLUTION: A switch body 10 has a push-button handle 40 operated by pushing, and push-operation of the push-button handle 40 is converted to a swing of a reversal handle 38 held in the switch body 10, and then the reversible handle 38 reverses a contact point alternately by the swing, A returning force is given to the push-button handle 40 by a returning spring 42 formed with a thin plate spring, and the returning spring 42 comprises fixed part 42a mounted on a rear face of the push-button handle 40, and a spring part 42b which is integrally extended from the fixed part 42a and resiliently contacted to the bottom face of a recessed portion 16 formed in the switch body 10. The spring piece 42b is capable of having a low spring coefficient and of ensuring longer life at low cost by forming the spring piece 42b with a thin and general spring material.
