ABSTRACT:
A thermostat for regulating the temperature of a space includes: means movable in the thermostat for sensing the temperature of the space; a switch device having means for switching between a pair of switching positions; and a pair of permanent magnet means for magnetic coupling relation with the switching means. Means is provided for translating the temperature sensing movement of the sensing means to the magnet means pair so as to attract the switching means from one of its switching positions to the other thereof. The translating means has a pair of means connected with each other for mounting the magnet means pair adjacent the switch device in the magnetic coupling relation with the switching means and also means for securing engagement with the sensing means so that the magnet means pair are conjointly movable with the sensing means and with respect to the switching device upon the temperature sensing movement of the sensing means to effect the attraction of the switching means from its one switching position to its other switching position.
An assembly for a thermostat is also disclosed.
