<p>PROBLEM TO BE SOLVED: To provide a switch device capable of delaying oxidation of abrasive powder while suppressing the reduction in fatigue characteristics of a leaf spring.SOLUTION: A leaf contact 5 is defined as a leaf spring applied to a switch device in which contact movement is generated while releasing energy stored in the leaf spring supported by a terminal. Silver plating 55 is applied to a contact portion with a terminal out of the leaf contact 5 and the silver plating 55 is not applied to a portion on which stress is concentrated in a process for releasing the stored energy.</p> |
