Allen-Bradley 800H-JR2BR 3-Position Maintained Selector Switch

Allen-Bradley 800H-JR2BR is a 30.5 mm (approximately 1.20 in) diameter rotary selector switch with three maintained positions, designed for rugged panel mounting in industrial environments. This non-illuminated operator uses a white standard knob and employs a KB7 cam, placing it in the 800H family of 30 mm/30.5 mm selector switches. It is rated for NEMA 4/4X/13 environments, making it suitable for demanding applications where washdown, dust, and moisture exposure are concerns. The unit supports reed-contact configurations including 1 NO 1 NC and 2 NO 2 NC options, enabling flexible signaling across the three positions. Typical uses include selecting machine modes (for example manual/off/auto) or interfacing with safety interlocks on equipment, providing reliable, locked-in operation with standard termination.
