PROBLEM TO BE SOLVED: To provide a pole switch in a case capable of improving cost reduction and the beauty of nature and having simplified installation legs for temporary setting on the bottom of the case. SOLUTION: This switch is a pole switch contained in the case which has the installation legs for temporary setting on the bottom of the case. The switch is positioned at the center of one side of the bottom of the rectangular case, is mounted with a breathing plug for airtightness inspection consisting of a nut and a bolt, and the small-diameter installation legs flush with the height of the breathing plug and appropriately spaced from each other so that balancing of the switch may be kept at the time of installing the installation legs on the ground, on the other side at a position facing the breathing plug.
