Abstract:
This switch device 100 comprises an insulation base plate 40, a spacer layer 30, a film base plate 20 having a fixed contact 23, and a dome-shaped click spring 10 having a movable contact 11 and disposed so as to cover the fixed contact 23. The fixed contact 23 comprises a central fixed contact 23a formed at the center of an upper-side surface of the film base plate 20, and a peripheral fixed contact 23b formed in the periphery of the central fixed contact 23a. The spacer layer 30 comprises a first layer 31 and a second layer 32, which have elasticity. The first layer 31 is provided between the insulation base plate 40 and an under-side surface of the film base plate 20 in a region where the central fixed contact 23a is formed, while the second layer 32 is provided between the insulation base plate 40 and an under-side surface of the film base plate 20 in a region where the peripheral fixed contact 23b is formed. The elastic modulus of the second layer 32 is greater than the elastic modulus of the first layer 31.
