United Electric (UE) Spectra 12 Vibration-Resistant Compact Pressure Switches

United Electric 12 Series hazardous location switches are ideal for operation in tough applications where space is at a premium. A Belleville spring assembly provides vibration resistance and prolongs switch life. It snaps over when pressure is applied and snaps back on pressure release.

The 316 stainless steel enclosure and hermetically sealed switch provide rugged protection from the environment. The easily accessible adjustment wheel allows in-line field settings. A 1 Amp switch is available for use in intrinsically safe circuits.
