Abstract

The invention provides a switch (4) composed of an irradiation mechanism (60) having an operation body and irradiating light from inner side of the operation body to a translucent section, The operation has an operation face (11) formed with a translucent section and a push section (23) shifts for pushing a switch (50) by push force onto the operation face (11), the operation body is composed of an operation member (10) of the operation face (11) and a push member (20) of the push section (23), the push member (20) is formed with the translucent material. Therefore, the switch (4) may prevent retraction from generating on the operation face (11), restrain asymmetry of lightness and improve push operation feeling.

Description

technical field [0001] The invention relates to switching devices. Background technique [0002] Conventionally, a switch device for performing a push operation has been widely used (for example, refer to Patent Document 1). [0003] Generally, such a switch device is configured to include an operating body (button) supported in a displaceable state, and to displace the operating body to push an internal switch. Thus, the operation body is integrally formed with an operation surface to which a pressing force is applied from the outside, and a pusher for pressing an internal switch in response to displacement caused by the pressing force applied to the operation surface. parts (e.g. ribs). [0004] [Patent Document 1] Japanese Publication No. 60-106196 [0005] In a device including a plurality of such operating bodies, characters, illustrations, etc. can be displayed on the operating surface of each operating body, and the processing, movement, etc. performed by pushing a...
