摘要： Thermostatic control apparatus comprising a switch, a switch body housing the switch, and an actuator arm extending from the switch body with the arm being movable between the first and second positions for opening and closing the switch. A thermostatic bimetal strip is spaced from the switch body, with one end of the strip being mechanically linked to the actuator arm. A support extends from the body for supporting the other end of the strip. A selectively operable adjustment cam engages the strip between its ends on the face of the strip adjacent the body, this cam being operable for adjusting the thermostatic strip to open and close the switch at various preselected temperatures. A spring biases the strip into engagement with the cam whereby changes in temperature of the strip cause the arm to move between its first and second positions thereby causing the switch to open and close.
