摘要： A trip-free manual reset thermostat wherein the travel of the reset device is limited so that the disc cannot be moved all the way to its reset position of stability. The reset device engages one side of the cantilever mounted flexible switch arm. Such switch arm is formed with an offset so that the disc-operated bumper engages the switch arm at a point spaced from the line of action of the reset bumper. When reset is attempted while the disc remains at temperatures outside the reset temperature range, the reset device and the disc-operated bumper produce a force couple which tends to maintain the switch in the operated condition.

摘要： A double pole thermostat is disclosed in which two switches are mounted in separate switch cavities separated by insulating material so that arc splatter cannot produce a conductive path between the switches. The switches are sequentially operated by a bimetallic snap disc with a first bumper extending between one switch and the disc, and a second bumper extending between the two switches. The second bumper provides lost motion to insure sequential operation of the switches and to insure that unequal contact wear will not result in one switch blocking the other switch open.
