A temperature sensitive normally open electrical switching device has a pair of normally isolated, current carrying leads. A casing defines a central cavity and encloses first and second electrodes which are electrically connected to separate ones of the leads. An electrically conductive, fusible pellet is positioned in the cavity and melts at a predetermined temperature to form an electrically conductive path between the electrodes, regardless of the orientation of the device. The first electrode is concave and the second electrode extends into the concavity formed by the first electrode.
