Allen-Bradley 800MR-N46QB Selector Switch 4-Position

Allen-Bradley 800MR-N46QB is a 30 mm, four-position selector switch (non-illuminated) with a keyed cylinder lock intended for panel mounting in industrial automation. The unit provides two normally open and two normally closed contacts (2 NO – 2 NC) wired through stab terminals for quick, solderless connections to control circuits, and it uses a cam code Q with a standard key code T100. Lock-in positions are at 3 and 4, securing the selected setting once rotated. This keyed selector switch is part of the 800MR family and is designed for environments where four discrete operator positions must be reliably retained and protected from unintended changes. Typical applications include selecting machine modes, routing signals, or enabling specific control functions within control panels and processing lines, such as conveyors, packaging lines, and automated packaging or processing equipment. The combination of four detented positions and keyed operation makes it well suited for applications where operator access needs to be controlled while maintaining clear, repeatable positions in the control circuit.
