Thermal Switches​

Thermal switches, which are also know as immersion thermostats are thermally sensitive bi-metallic switches housed in a rugged brass or stainless steel case. DECA Manufacturing has acquired Thermtrol's complete line of thermal switches and is now manufacturing these devices at our plant in Ohio.

 

The switches are manufactured to either make or break an electrical circuit at a factory pre-set temperature and they reset automatically on cooling. Some devices are ideally suited as regulating thermostats, which cycle open and closed more rapidly to maintain a temperature level. Other devices can be used as over-temperature protectors to limit a temperature from exceeding a predetermined value. DECA  offers complete design flexibility for custom immersion thermostats by drawing from an extensive inventory of standard components and building the thermostat that is correct for your application. Our products include: 
 

  • Regulating Thermostats

  • Overtemperatures Thermostats

  • Standard

  • High Contact Capacity

  • High Temperature High Contact Capacity

  • Miniature Thermostats

Numbering System

Our thermal switches are identified with a numbering code that indicates:

  • Switch code type and material

  • Housing style 

  • Collar code

  • Status

  • Set temperature

  • Termination options

​

Testing and quality control

​

We test our temperature switches using an oil bath; or for products with higher temperature ratings, an oven is used.  Data is logged for tracking purposes.
