Which Switch is Best for You?

Senasys manufacturers a large variety of switches for HVAC systems, including our TC Switch (Firestat), bulb and capillary thermostat, bi-metal switches and micro snap action switches.

Temperature HVAC Switches

Senasys manufactures a wide array of temperature switches for HVAC systems including bulb and capillary thermostats, bi-metal snap disc thermostats, and duct limit switches.The temperature switches for HVAC systems typically are used as a fan or lime when a pre-defined temperature is reached.

Duct Limit Switches

 

Our TC Adjustable Limit Switches, also known as a Firestat, are used to shut down heating, ventilation and air conditioning equipment. They are shut down once the air temperature rise exceeds the units pre-set limit.

Senasys is current in the research and development stage for a duct fan switch, which will turn on equipment when the temperature exceeds the limit in the HVAC equipment, such as a fan of a blower.

Air Flow Switches for HVAC Systems

JMP sail switches are commonly used as an air flow switch for an HVAC system. When air flow is lost in the system, the sail switch will trigger an appliance such as a booster fan to restore air flow. The sail switch is a stable, low cost solution for sensing air flow and pressure.

HVAC Float Switch

The JMP division of Senasys also offer condensate/styrene float switches which are commonly used to sense a pre-defined water level of a dehumidifier drip pan. When the level is met, this simple HVAC float switch kicks on a pump to lower the water level or shuts the appliance down. The HVAC float switch is designed with a stainless steel left and styrene float for an economical solution to monitor liquid levels.
