Rod-type switch

摘要

A rod-type switch including: a tube-like body; a conductor conducting tube fixed in the middle part of the body; a contact having on one end thereof an insulating rod extending inside the conductor tube, the other end of the contact projecting from one end of the body; a spring resiliently the contact biasing so that a part of the contact is caused to project from the body; and an electrode rod supported by the body while insulated therefrom and biased in a direction of the conductor tube by a spring so that a contact portion of the rod contacts an end of the conductor tube. As a result of the construction, an electrical circuit is formed by the body, the conductor tube and the contact portion of the electrode rod, and a switch is formed by relative movement of the contact portion with respect to the end of the conductor tube.
