WIPO Patent Application WO/2012/049868

Kind Code:

A1

Abstract:

The problem is to provide a switch capable of handling intermediate load switching and having a small operation sound. To solve this problem, a switch comprises: a rotation contact piece (40) having one end thereof set as a rotation fulcrum, and the other end thereof provided with a rotation contact point; a rotating member (30) having the other end thereof set as a rotation fulcrum; a coil spring (50) having one end (51) fastened to one end of the rotating member (30), and the other end (52) fastened to the middle section of the rotation contact piece (40); and a push button (80) that with the lower end surface thereof (82) pushes the one end of the rotating member (30) down, and is supported so as to be capable of sliding vertically. The push button (80) pushing the one end of the rotating member (30) down causes the rotation contact piece (40) to invert, and the rotation contact point (43) to come into and out of contact with a fixed contact point (28). Specifically, a position-restricting part (31) provided on the rotating member (30) contacts the coil spring (50) when the rotation contact piece (40) inverts, and while maintaining a state of contact with the coil spring (50), causes the rotation contact point (43) to contact the fixed contact point (28).
