Damper Position Indicating Switch

The TS-470 Series damper position switch consists of an encapsulated mercury switch mounted on a 1/2" (1.3 cm) damper shaft crank arm. The TS1-470 Series includes the same switch, mounted on a 1" (2.5 cm) crank arm. They are mounted on a horizontal damper shaft to provide opened/closed indication. Switch contacts are normal when the cable end of the switch is horizontal or above, and makes when the cable end drops more than 15º below horizontal. These switches are ideal for Building Automation System BAS and HVAC applications.
