Overview
The Allen-Bradley 800T-QH24W is a 30.5 mm illuminated pushbutton switch from the Series T product line, designed for harsh industrial control environments. This metal-bodied pilot light integrates a white LED lamp and operates at 24V AC/DC, providing bright, energy-efficient visual feedback in machine control panels, process automation systems, and industrial equipment.
Key Features
- 30.5 mm metal pushbutton with integrated LED illumination
- Series T design for 24V AC/DC full-voltage operation
- Push-to-test function allows operators to verify lamp operation without triggering the circuit
- Type 4/13 NEMA rating for wet/corrosive environments
- Single NO/NC contact block (1 NO, 1 NC) configuration
- IEC 947-5-1 compliant switchgear component
