PROBLEM TO BE SOLVED: To provide a switch apparatus which is prevented from getting into operational failure due to deformation or fusion of an operational member constituted of resin parts, does neither need to use costly and heat resistant material for the operational member nor need to use costly and arc resistant material for contacts, and is made small and economical. SOLUTION: A slider 11, which is an operational member, is made to drive a movable contact 16 of a heat generating source through a spring 17, so that the slider 11 and the movable contact 16 are prevented from being brought into directly contact with each other in the state that a load is applied. The movable contact 16 is turned over and contact is opened or closed by making a pressing point to the movable contact 16 get over a supporting point of a fixed contact and before and after the turning over, the contacts are mutually slid. |
