Different Types of Adjustable Temperature Switches

Senasys is a leading manufacturer of temperature switching solutions that are delivered worldwide. Using bi-metal, fluid or electronic sensing elements, Senasys offers a variety of products to fit your application requirements.

Adjustable Duct Limit SwitchAdjustable Duct Limit Switch

Our TC Adjustment Duct Limit Switch is used to shut down heating, air conditioning and ventilation equipment when the air temperature rise exceeds the pre-set limit. The switches can be adjusted to detect a temperature from 100-250°F. Commonly installed into air ducts, the circuit opens on temperature rise, when the specified temperature is reached.  Once this temperature has been reached the limit switch requires human intervention to reset the lever.
