Operation switch

摘要

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.

主权项

1. An operation switch comprising:
an operation unit disposed on a front surface side of a panel and operated by an external pressing force; a switch unit having a first end configured to be attachable to and detachable from the operation unit from a rear surface side of the panel, said switch unit including a second end opposite said first end; 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; 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, the release lever being configured to be operated from the second end of the switch unit; and a to-be-pressed portion accessible at a location furthest away from the first end, the to-be-pressed portion protruding from the second end of the switch unit, and configured to be pressable from said second end to operate said release lever to release said latching state, wherein the latching unit is formed of a connection portion with a hole, the latching receiving unit is formed of a rib that protrudes outward from the switch unit, and when an engaging surface of the rib is latched in the hole, the operation unit and the switch unit are latched to each other and a releasing surface presses and expands the connection portion.
