Altitude Pressure Switch A45C Series

The A45C is our most sensitive skeletal (no pressure fitting) altitude switch for use with air or inert gas. This unit features a Ni-Span-C capsule for superior setpoint stability over a wide range of temperatures. Three standard mounting options are available: diamond bracket (shown), side bracket and integral tapped holes. Typical applications include aircraft cabin pressure systems, nitrogen radar cooling alarms and atmospheric research balloons.
