However, when the door switch as a product is transported, the collar member 49 is If the attachment hole 48 is configured to be removed in the front-rear direction (front to back) of the main body case 41, the collar member 49 is press-fitted into the attachment hole 48. However, in addition to the mounting hole 48, when trying to provide a mounting hole that extends in the left-right direction of the main body case 41, the collar members 49 interfere with each other so that the mounting hole that extends in the left-right direction is provided. There is a problem that the door switch S as a safety switch cannot be mounted on the side surface.

本発明は上記の問題点を解決するものであり、その第１の目的とするところは、操作キーをキー挿入口に入れようとした場合に、操作キーはキー挿入口に容易に入り、操作キーがヘッドケースに衝突するといった不具合が防止できる安全スイッチを提供することである。 The present invention solves the above-mentioned problems.
