Abstract (en)
[origin: EP0678891A1] A bimetallic switching element designed to open contacts at a specific level of current has a circular housing with a movable contact on a bimetallic disc (6) and a fixed contact (11) on the cap (7). Mounted directly below the bimetallic disc is a snap action disc (3) that is produced from a relatively low conductivity metal such as steel or brass. The resistance value of the disc is set by forming slots in the disc. At a specific value of current the disc responds to snap over and so opens the contacts. <IMAGE>
