Claims

[Scope of utility model registration request]

(1) A fixed contact forming the other electrode is provided at a position opposite to a fixed peripheral reversible contact piece forming one electrode, and a leaf spring is pressed into engagement with the fixed peripheral reversible contact piece when the operating member is pressed. In a click switch of a camera that causes both electrodes to contact each other by elastically deforming the electrodes, the pressing position of the operating member is shifted from the fulcrum position generated when the leaf spring and the peripherally fixed reversible contact piece are pressed into contact with each other. A click switch that features:

(2) A click switch for a camera, characterized in that a second switch is formed by the leaf spring and the peripherally fixed reversing contact piece.
