Description Technical Specs
 

Honeywell S637A1004 Sail Switch with 1" x 3" Sail

The S637 Sail Switches respond to the air velocity in heating or warm air ducts, such as used in farm crop dryers. The switch completes a 24V or line voltage burner control circuit only when the blower or fan has produced a predetermined air velocity.

Features
- Micro Switch SPDT snap switch is operated by metal sail inserted in an air stream.
- Sail can be trimmed to one-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
