Problems solved by technology

[0003] In the switch of Patent Document 1, the ratio of the volume of the rotary handle body and the coil spring used as the return spring body to the whole switch is large, and it is difficult to reduce the size of the switch.
[0004] In particular, since the movable contact spring is disposed between the recess of the case and the spring body for recovery, the thickness of the switch becomes large due to the contact structure composed of the movable contact of the movable contact spring and the fixed contact of the recess. , it is not easy to realize the thinning of products equipped with switches
[0005] In addition, in order to configure the switch, a case, a rotary handle body, a return spring body, and a movable contact spring are required, and there is a problem of a large number of parts.

Abstract

A switch provided with an operation body (30), a base (10), and conductive elastic members (42a, 42b) which are housed in the concave part (11) of the base (10) and on which secured contact parts (41a, 41b) and moveable contact parts (42a, 42b) having parts (44, 44a, 44b) to be driven and expandable parts (43a, 43b) capable of expanding by means of the input from the drive part (33) of the operation body (30) to the parts (44, 44a, 44b) to be driven are disposed. When a load is applied to the operation body (30) at a first position in which the moveable contact points (45a, 45b) are separate from first secured electrodes (21, 22), the operation body (30) can be moved to a second position. Meanwhile, when the load applied to the operation body (30) is removed at a second position in which the expandable parts (43a, 43b) of the conductive elastic members (42a, 42b) are compressed and the moveable contact points (45a, 45b) come into contact with the first secured electrodes (21, 22), the operation body (30) is automatically returned to the first position. As a consequence, it is possible to thin the switch and to reduce the number of components.

Description

technical field [0001] The present invention relates to a switch, in particular to an ultra-small switch for electronic devices such as mobile phones, smart phones, and digital cameras, which is thin and has a small number of parts. Background technique [0002] Patent Document 1 discloses a switch device including: a housing having a shaft protruding from the bottom surface of an annular recess provided with a fixed contact; a concave portion having an operating body; a substantially annular recovery spring body inserted into the shaft portion of the concave portion of the case; a movable contact spring having a movable contact disposed on the case The space between the shaft portion and the inner peripheral surface of the rotary handle body. [0003] In the switch of Patent Document 1, the volume ratio of the rotary handle body and the coil spring used as the return spring body is large relative to the entire switch, making it difficult to reduce the size of the switch. ...
