Embodiment 1

[0090] The operation sound when the contacts were opened and closed was measured for the five example samples having the structure of the first embodiment and the five comparative example samples in which the rotating member was not bent and the stopper was not formed. In addition, in the case of the comparative example in the no-load state, the coil spring did not come into contact with the rotating member.

[0091] As a measurement method, the sample was placed on a 6.35 mm-thick suction material placed on the floor of an anechoic room. A mark was placed at a position 300 mm directly above the sample, and the operating sound at the time of opening and closing was measured.

[0092] As a result of the measurement, the operating sound of the example was 21.0 db on average, and the operating sound of the comparative example was 34.4 db on average, and it was judged that the operating sound could be reduced by 40%.

[0093] In addition, by expressing the correlation between the...

Abstract

It is an object to provide a switch that can respond to opening and closing of medium load and that has small operating sound. There is provided a switch including a movable contact piece (40) having one end as a supporting point of turn and the other end arranged with a movable contact (43); a turning member (30) having the other end as a supporting point of turn; a coil spring (50) halving one end (51) locked to one end of the turning member (30) and the other end (52) locked to an intermediate portion of the movable contact piece (40); and a push button (80) being supported to be slidable in an up and down direction and for pushing down the one end of the turning member (30) with a lower end face (82); the movable contact piece (40) being inverted by pushing down the one end of the turning member (30) with the push button (80) so as to make the movable contact (43) approach and separate to and from a fixed contact (28). In particular, the turning member (30) includes a position regulating portion (31) that is brought into contact with the coil spring (50) when the movable contact piece (40) is inverted and that brings the movable contact (43) into contact with the fixed contact (28) while maintaining a contact state with the coil spring (50).

Description

technical field [0001] The invention relates to a switch, in particular to a button switch with low operating sound. Background technique [0002] Conventionally, as a push button switch, by pressing down a rotating member with a push button, the movable contact piece is reversed by the spring force of a coil spring connected to the rotating member, so that the movable contact provided on the movable contact piece and the Contact and separation of fixed contacts (refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 9-120731 [0004] However, in the push button switch described above, when the movable contact provided on the movable contact piece comes into contact with the fixed contact, a loud operation sound is generated. Contents of the invention [0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a switch with a low operating sound. ...
