Description

  The present invention relates to a switch operation device that operates a lever portion of a lever switch via an operation member, and an electronic device such as a digital camera including the switch operation device.

  Some electronic devices such as a digital camera include a switch operation device that performs switching by operating a lever portion of a lever switch by rotating an operation member and detecting the operation of the lever portion with the lever switch.

  As a conventional switch operating device of this type, a device in which a part of an operating member that operates a lever portion of a lever switch is formed of an elastic member has been proposed (Patent Document 1).

  In this proposal, even when a part of the operating member interferes with the lever part of the lever switch when the switch operating device is assembled and the lever part is pushed in a direction different from the operating direction, the elastic member is elastically deformed to damage the lever switch. It can be prevented.
