Honeywell Commercial S437A1009 HVAC Controller Sail Switch

Honeywell S437A1009 HVAC Controller Sail Switch delivers reliable air-control sensing for commercial systems. This precision sail switch is designed for broad voltage support and SPST operation in demanding HVAC environments.

UL and CSA approved, it mounts on a duct wall and fits a compact footprint (3-3/4 in W x 2 in D x 2-15/16 in H). It supports multiple input voltages including 24/120/240 VAC and 6/12 VDC, with a wide current range suitable for various control applications, including 8 A at 120 VAC, 5.1 A at 240 VAC, 2 A at 24 VAC, 15 A at 6 VDC, and 7.5 A at 12 VDC (full load). For inrush or stalled conditions, it handles up to 48 A at 120 VAC and 30.6 A at 240 VAC (locked rotor). Insertion length is 3-1/2 in, and the operating velocity is 1900 feet per minute, with a temperature rating up to 150°F.
