When the force applied to the a is increased, as shown in FIG. 5, the bowl-shaped elastic body 28a does not move while being depressed, that is, does not move while the fixed contact 27a is short-circuited, and the drive plate 32 moves the pivot of the swing member 35b. Further, the force applied to the thick-film bowl-shaped elastic body 28b increases and the bowl-shaped elastic body 2b is rotated.
When the elastic force exceeds 8b, the bowl-shaped elastic body 28b is concavely deformed and deformed, and the movable contact 31b descends, thereby short-circuiting the fixed contact 27b as the second contact.
