Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switch apparatus capable of preventing continuous abnormal heat generation of a movable contact by changing a contact state of the movable contact with a fixed contact at high responsiveness to the abnormal heat generation of the movable contact.SOLUTION: A switch apparatus 1 includes a movable plate 4 having movable contacts 5a-5c and a movable member 3 for selectively contacting/separating the movable contacts 5a-5c to/from a fixed contact 8 by operating the movable plate 4. A plurality of springs (energization members) 6, 7 for energizing the movable plate 4 to the fixed contact side are arranged in the movable member 3, a fuse member 9 to be deformed at a predetermined temperature to change energization force of the spring 6 is interposed between the spring 6 and the movable plate 4, and the fuse member 9 and the spring 6 are arranged in the vicinity of the movable contact 5a.SELECTED DRAWING: Figure 2
