Allen-Bradley 800H-JR2KE7B Selector Switch Maintained

Allen-Bradley 800H-JR2KE7B is a 30.5 mm, 3-position maintained selector switch with a white standard knob and KE7 cam, designed for panel mounting in industrial control circuits. It carries a NEMA 4/4X/13 rating, enabling use in harsh environments with dust, moisture, and washdown exposure. The maintained action provides stable, repeatable positions at each of the three stops, making it suitable for indicating and selecting machine states without continuous actuation. This model aligns with standard 800H 30 mm contact-block systems, where the exact contact configuration depends on the installed blocks (for example, configurations including 1NO 1NC or 2NO 2NC are common in compatible assemblies). The KE7 cam code and white knob contribute to clear operator feedback, while the 800H platform emphasizes interchangeability with related contacts and actuators within the 30 mm selector switch family.
