Patent abstract
A thermostat has a switch, a temperature sensor, a lever, a spring, and a control plate. The sensor generates a force to operate switch in response to the ambient temperature. The lever having an arm turns with the force from the sensor to open/close contacts of the switch. The first end of the spring is hooked to the lever to bias a force to the lever in the direction opposite to the force from the sensor. The control plate is hooked to the second end of the spring and is disposed on the lever, allowing a force for turning the lever to increase or to decrease due to turning of the control plate. The control plate turns the arm to perform the forced switch-off operation.
