It's item number 12266 in the Siemens accessory lineup, not a standalone motor starter but a control station component that mounts into an enclosure or operator station. The cage clamp connection means you push a ferrule or solid wire into the clamp — no screw tightening, no torque spec to chase. That saves time on a panel build where you're wiring a dozen pushbuttons into the same row. No stock-holding claim here; we quote per your requirement. ## Where it fits in the panel This pushbutton belongs on a motor starter control station — think start/stop stations on conveyors, pumps, or machine tools where a yellow mushroom head signals an emergency or lockout function. The 1NO contact is typically wired into the control circuit as a reset or acknowledge input. The yellow actuator is a visual cue: in a row of black/red pushbuttons, yellow stands out for a specific function.","metaTitle":"Siemens 3RA9012-5BL37 Mushroom Pushbutton, 1NO, Cage Clamp","metaDescription":"Siemens 3RA9012-5BL37 GM-SET mushroom pushbutton, yellow, 1NO contact, cage clamp connection.
