摘要： A thermostat is disclosed which has a moveable backstop in order to fulfill a requirement in many countries that a 3 millimeter contact gap be provided for the thermostat to qualify as an electrical disconnect. The thermostat is comprised of a setting wheel having a ramp formed thereon, a lever, a plunger and a backstop slidably connected to the frame of the thermostat. The lever contacts the ramp on the setting wheel and is moved by rotation of the setting wheel. One end of the plunger is in contact with the lever, the other end being in contact with the backstop. When movement of the setting wheel causes movement of the lever, the plunger is moved in an axial direction thereof, thus causing movement of the backstop. The ramp is positioned on the setting wheel such that the backstop is moved when the setting wheel is turned to an off position.
