The Eaton Cutler-Hammer E22PB2A Pushbutton Operator is a 22.5 mm flush red momentary pushbutton designed for industrial control panels. It provides momentary start/stop operator input in PLC panels, motor control stations, conveyor systems, and automation equipment where a momentary signal is required. This operator features a plastic base, a red flush actuator, and non-illuminated operation, mounted in a 22.5 mm opening. It is an operator-only device and requires pairing with an appropriate contact block to complete the circuit. Manufactured by Cutler-Hammer (Eaton) with MPN E22PB2A, it is intended for use in industrial control panels and OEM machine interfaces, supporting frequent actuation in manufacturing environments. Typical applications include manufacturing equipment, packaging machines, material handling systems, motor control centers, and general-purpose industrial control panels. The device carries an industrial-duty mechanical life characteristic per the E22 series and is commonly used for operator interface replacement, panel repair, or control system retrofit within automation and machine control systems.
