Air Velocity Sensors
S637 Sail Switch
S637 sail switches respond to the air velocity in heating ducts such as farm crop dryers. They complete a 24V, or line voltage, burner control circuit when a blower or fan has produced a predetermined air velocity.

Features & Benefits:- MICRO SWITCH™ SPDT snap switch is operated by metal sail inserted in an air stream
- Has a set of normally closed (NC) contacts that can be used to energize a signal or warning circuit when the velocity drops
- Sail can trimmed to half the original size to double the velocity required to close the snap switch contacts
- Switch differential can be manually adjusted by turning a knurled knob on the snap switch
- A conduit knockout is located on each end of the case for wiring convenience
