SWITCH MECHANISM, LENS BARREL, AND IMAGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a switch mechanism capable of suppressing malfunctions and breakage of electrical components caused by penetration of static electricity.SOLUTION: A switch mechanism is mounted on a mounting member 21 and operated from the exterior of the mounting member 21. The switch mechanism comprises: an operated part 310 operated from the exterior of the mounting member 21; a base 321 located inside the mounting member 21 and moving by an operation of the operated part 310; a position regulation member 323 fixed with the base 321 and regulating a movement position of the base 321; and a coupling part 322 fixed with the base 321 and operating a switching member located inside the mounting member 21. The base 321 and the coupling part 322 are formed of a non-conductor, and the position regulation member 323 is formed of a metal having a spring property.
