ABSTRACT:
A constant-on variable-stroke refrigeration thermostat is disclosed wherein the toggle spring-biased operating lever has a fixed-position stop when the contacts are open and a variable-position stop when the contacts are closed, and wherein an air gap is provided between the actuator prong of the operating lever and the moveable contact blade of the switch contacts to allow the operating lever to travel downwardly with increased momentum before the switch contacts are opened. The primary advantage provided by the present invention is that the thermostat is of a much simpler construction, which results in a lower cost and a higher reliability.
