Allen-Bradley 800TC-QBH2B Momentary Push Button

Allen-Bradley 800TC-QBH2B is a 30 mm illuminated momentary push button with a blue LED, designed for industrial control panels and machine interfaces. This full-voltage device operates from 12–130 V AC/DC and uses a 1NO-1NC contact configuration, enabling simple start/stop or signaling logic in control circuits. The push button features an extended-head operator and a finger-safe guard for increased protection against accidental actuation in tight panel spaces. The blue LED lamp provides immediate visual feedback when energized, enhancing operator awareness in noisy or distracting environments. Equipped with a full-voltage power module, it supports reliable illumination and signaling from a single supply, making it well-suited for applications such as start/reset signaling on conveyors, packaging lines, and other automated equipment. Part of Allen-Bradley’s 800T/800TC family, this 30 mm push button is built for robust panel mounting in demanding industrial settings, combining a compact footprint with dependable momentary action and clear LED indication.
