Two Stage Bulb & Capillary Thermostats
The Type 352 series of Bulb and Capillary thermostat utilizes two separate switches for two stage or double pole switch action. The two switches can be any combination of SPDT Automatic Reset Switches, and/or 2 SPST Manual Reset Switches.
The switch can be used for a combination of heating and cooling, or fan and limit, from one thermostat; or use it for three phase or double line breaks.
QUALITY AMBIENT COMPENSATION
Our capillary thermostats also offer the option of being ambient compensated to offset the differential in temperature which keeps our thermostat controls more accurate as it’s environment changes.
CERTIFIED
Senasys takes pride in quality control and reliable operation of our products. Every switch is individually 100% tested before it leaves the plant. Our capillary thermostats are UL & cUL approved.
CUSTOM OPTIONS
Capillary thermostat switches built by Senasys can also be built to customer specifications. This ensures you get the exact control you want without paying for features you don’t need.

The Type 352 series of Bulb and Capillary thermostat utilizes two separate switches for two stage or double pole switch action. The two switches can be any combination of SPDT Automatic Reset Switches, and/or 2 SPST Manual Reset Switches.
The differential between the switches can be factory set very close for Double Pole applications or wider for Multistage applications. Wiring the two double throw switches in series allows the 352 to be used where a very large differential between on and off is required. The two switches can also be wired together to create a heating/cooling thermostat with dead band.
The combination of an automatic reset and a manual reset switch is ideal for applications where the automatic reset switch is the controlling switch and the manual reset switch is used as a safety or limit switch.
