Allen-Bradley 800H-R1A Pushbutton

Allen-Bradley 800H-R1A is a 30 mm booted-head pushbutton from the 800H family, shipped with a green operator cap and a dual-contact arrangement that provides one normally open (NO) and one normally closed (NC) circuit path, designed for momentary actuation in industrial panels. The booted head differentiates this model from bootless variants in Rockwell Automation's catalog, while the panel-mount design supports standard control panels and machine housings, with the green cap aiding quick visual identification in multi-button layouts. Electrical configuration 1 NO + 1 NC enables simultaneous control of two functions—such as a go/stop or start/safing scheme—without requiring a second actuator, simplifying panel wiring and improving reliability in enclosures where space is limited. As a momentary 30 mm pushbutton, the 800H-R1A preserves the familiar mounting footprint and interchangeability with other 800H variants, allowing straightforward replacement or retrofit within existing installations.
