Conduction Type Thermal Switch Products
Bilbee Controls conduction type thermostats do not use typical bonded bimetal strips. The contacts are opened and closed by expansion and contraction of the base plate resulting in vertical movement of the specially-formed, low-expansion thermal spring. as shown in the cut-away animation below.

Animation Details:
In the first segment of the animation you see an adjustable type thermostat with an extended torque arm. As the current temperature rises to the set "cut off temp" the contacts slowly separate. When the adjustment control rotates, the internal upper contact is mechanically lowered which creates a further delay in disconnect thus requiring additional thermal energy / higher temperature.
The second segment of the animation displays a fixed setting thermostat. The fixed position is calibrated at the factory to meet the customer's specifications. This type is well suited for applications requiring precision control at a factory-set temperature. An adjustment set screw enables the customer to trim the calibration to compensate for mechanical and thermal variations in the device at the time of installation. Fixed setting arrangement also prevents accidental or vibration movement of adjustments.

Adjustable Units: Known widely as the B-200 conduction type thermostat. If our pre-designed units do provide a solution, a development unit will be shipped out for customer adjustment then returned for production. Search our database of pre-designed products to see if one suits your needs.More Details
Fixed Units: - Pre-set with no adjustability feature. Set for the range of Rm-Temp to 600F with a tolerance of +/- 5% of the setting. The B-1200 series units are required to be sealed by the customer, while the A-1200 series are sealed at the factory.More Details
Rotational limits limit the rotational range of the adjustable units to fit product design. This allows customers the flexibility needed to prevent the control from dictating product design.More Details
