Overview
The United Electric J6-272 is an industrial-grade pressure switch designed for general-purpose pressure monitoring and control. This NEMA 4X-rated unit features a single SPDT switch output and operates across a 0–250 PSI setpoint range, making it suitable for pump control, compressor protection, and emergency shutdown circuits. With phosphor bronze bellows, nickel-plated brass connections, and robust internal construction, the J6-272 delivers cost-effective reliability in demanding environments.
