PROBLEM TO BE SOLVED: To provide an on-vehicle switch used mainly for operation of various on-vehicle electronic apparatus which ensures stable switch contact and reliable operation.SOLUTION: The on-vehicle switch has a metal movable contact 14 formed with a through-hole 14A in a substantially central part thereof. Even when a relatively large foreign matter 7 enters in the vicinity of the center between the movable contact 14 and the opposing fixed contact 16, the foreign matter 7 enters into the through-hole 14A. Thus, the movable contact 14 around the through-hole 14A reliably comes into contact with the fixed contact 16. Accordingly, an on-vehicle switch ensuring stable switch contact and reliable operation is achieved. |
