A push-button switch () is arranged such that, once a user presses an operation button (), a switch body () performs an operation, and light from an LED () passes through a transmission plate () and then illuminates the operation button (). A structure () is provided on a lower surface () of the transmission plate () to refract the light from the LED () so that the refracted light is reflected within the transmission plate () and then guided to an upper circumferential wall () of the transmission plate ().

A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.

Push button switch

An operation switch where a switch unit can be separated from an operation unit in a simple manner even when the operation switches are densely fitted is disclosed herein. The operation switch of the invention includes an operation unit that is disposed on a front surface side of a panel and operated by external pressing force, a switch unit that can be separated from a rear surface side of the panel from the operation unit, a latching unit formed on an external circumferential surface of the operation unit along an axial center direction, a latching receiving unit which is formed along an external circumferential surface of the switch unit and to which the latching unit is latched, and a release lever that releases a latching state of the latching unit and the latching receiving unit so that the switch unit is separated from the operation unit.

Operation switch

A switch driving portion includes a lever link mechanism which as a pair of lever members respectively rocking about a rocking fulcrum by interlocking with a push button portion when the push button portion is pushed and arranged so as to be faced each other and in which the both lever members are connected each other at their faced ends by joint members so that they can be folded and slid and a switch operating member for opening or closing a built-in switch when the lever link mechanism is rocked by pushing in the push button portion.
