Allen-Bradley 800T-QT10B Push Button Switch 30mm

The Allen-Bradley 800T-QT10B is a 30.5 mm blue pilot-light push-button switch from the 800T family designed for rugged industrial control panels. It features a built-in incandescent pilot lamp and is rated for full 120 VAC operation, with a dual-contact block configured as 1 normally open and 1 normally closed contact for straightforward start/stop signaling. This push-to-test operator is rated Type 4/13 for environmental protection, making it suitable for harsh manufacturing environments and washdown areas. The 30.5 mm (approximately 1.20 in) bezel fits standard 30 mm mounting cutouts and aligns with Allen-Bradley’s modular 800T components, ensuring compatibility with common replacement parts. Typical applications include equipment control panels in manufacturing, packaging, and material handling, where a clearly illuminated indicator and reliable two–circuit operation are required for safe, verifiable actuation.
