Allen-Bradley 800H-DR Pushbutton Momentary Switch

The Allen-Bradley 800H-DR is a 30 mm mushroom-head pushbutton operator that provides a momentary input for industrial control panels. As part of the 800H family, this model is designed for panel mounting and is used to generate a quick, one-shot signal when pressed in machines and process equipment. The DR designation identifies the mushroom-head style within the 800H line, and typical installations pair the pushbutton with standard 800H mounting hardware and contact blocks; common accessory references include 800H-N142 thrust washer, 800H-N146, 800H-N148, and gasket F-14963. Applications span general start/stop signaling, reset actions, and other momentary control tasks where a brief operator input is required. Because the 800H-DR family encompasses several sub-models, verify the exact variant (such as DR3, DR7C, or DR1JA) to confirm any illumination options and contact configurations specific to that version. This ensures correct compatibility with your control panel layout and the appropriate auxiliary components for reliable industrial use.
