Allen-Bradley 800MS-12HX2BS Selector Switch 30mm

Allen-Bradley 800MS-12HX2BS Selector Switch is a 30mm industrial control device from Rockwell Automation designed to provide operator selection within electrical control circuits. As part of the 800MS family, it functions as a multi-position selector used to indicate or select operating states in machinery and production lines. The exact configuration—such as the number of positions, maintained versus momentary operation, contact arrangement, and whether it is illuminated—varies by the 12HX2BS variant and is defined in the official product documentation. Mounted in standard 30mm panel cutouts, these switches are commonly integrated with complementary control components to form a complete operator interface within automation panels. When replacing or upgrading, verify compatibility with your control panel and the applicable electrical ratings for your application, and reference the specific data sheet for the 12HX2BS configuration to ensure correct mounting, wiring, and actuation characteristics.
