  • Manual switch with timed electro-thermal latch release
    Patent number: 4345233
    Abstract: A momentary ON rocker button switch (2) with bimetal detent latching (36) in the ON position and releasable by a heater (42) wound on the bimetal (36), the heater (42) being controlled through the output of a solid state timing circuit (TC, R1, C1) housed in the switch which is energized upon closure of the switch contacts (14a, 18).

  • Remote control electro-thermal actuator switch
    Patent number: 4337450
    Abstract: An electric switch having an actuator (24) normally manually operable to close and open a load circuit is provided with an electro-thermal device (42) of the coil (46) heated bimetal (43) type connected to external terminals (16, 17) adapted to be energized by a remote switch and power source to actuate the manual actuator (24) back to its open position.

  • Thermostatic control device
    Patent number: 4166996
    Abstract: Movement of the diaphragm pad occasioned by change in pressure within the diaphragm in response to a change in sensed temperature causes the bowed actuating spring to increase or decrease the degree of flexure to actuate the switch. In order to accommodate the pressure variations induced by a wide range of ambient temperature conditions the diaphragm is preloaded by a second bowed spring. A cam mechanism can be provided to vary the flexure of the preloading spring to thereby adjust the temperature at which the switch will be actuated.
