Abstract
A dual contact thermostat includes a bimetallic strip that partially controls two sets of contact points. An adjustable temperature actuator engages the contact points whereby the activation temperature of each set of points when the points are first closed is determined by the bimetallic strip in combination with the adjustable temperature actuator.
Claims20
An adjustable thermostat comprising
- a bimetallic strip;
- a first set of contact points and a second set of contact points;
- and
- a temperature setting actuator movable to a plurality of temperature settings;
- said bimetallic strip engaging and controlling the position of a first side of each of said first and second set of contact points whereby said first side of said contact points move with movement of said bimetallic strip;
- said temperature setting actuator engaging and determining the position of a second side of each of said contact points such that said second side of said contact points move in response to movement of said temperature setting actuator;
- each of said contact points changing condition by opening or closing as a function of said bimetallic strip and the temperature setting of said temperature setting actuator with said first set of contact points changing condition at a first temperature and said second set of contact points changing condition at a second temperature different from said first temperature.

- said temperature setting actuator engaging and determining the position of a second side of each of said contact points such that said second side of said contact points move in response to movement of said temperature setting actuator;
- whereby each of said contact points open and dose as a function of said bimetallic strip and the temperature setting of said temperature setting actuator;
- and wherein said temperature setting actuator is rotary and includes a cam surface for displacing said temperature setting actuator whereby rotation of said temperature setting actuator causes said second side of said contact points to be displaced altering the temperature at which said contact points open and close.
