Description
The ASCO P159A121X1X13F0 Proof Of Closure Switch with Arm is created to assure the complete closure of the valves or dampers in HVAC systems. Fitted in the control assembly, it gives a better electrical signal to the mechanical components when they close. Having 14 seconds of activation and 120V operation, the switch improves right and stable operation. It is designed to have a solid arm mechanism which ensures that it remains operational at normal conditions. This proof-of-closure switch allows the effective operation of the connected equipment in that it ensures appropriate system control and proper operation.
