ABSTRACT:
There is disclosed a mercury switch for use in thermostat applications. The switch has a hollow housing fabricated from glass and is positioned in the horizontal plane when in an operating orientation. The switch has a first common electrode within said housing and extending parallel to the horizontal plane with a terminal end extending from the housing. Positioned above the first electrode is a second shorter electrode with a third longer electrode positioned above said second electrode said third electrode being longer than said second but shorter than said first. Positioned above the third electrode is a longer fourth electrode. Essentially, major portions of the electrodes within the housing are parallel to each other. A charge of mercury is in the housing and operates to make contact between the electrodes in four operating modes indicative of thermostat operation for control of a heat pump, furnace and air conditioner. In a first mode the first electrode is in contact with the second to activate a furnace or air conditioner. In the second mode, based on a further tilt of the switch, the first electrode is in contact with the third to activate a heat pump. In the third mode the first electrode is in contact with the third and fourth to activate a heat pump and an air conditioner or furnace. In the fourth mode the first electrode is in contact with the fourth to activate the air conditioner or furnace. The switch is mounted on a bimetallic spring which expands and contracts to tilt the switch to cause the above noted operation.
