Allen-Bradley 800T-H48 Key Selector Switch

Allen-Bradley 800T-H48 is a 30 mm diameter two-position selector switch from the 800T family, designed for rugged operator input in industrial control panels. It is a keyed, cylinder-lock unit (commonly configured with a D018 key code) and is non-illuminated, intended to be used with separate 800T contact blocks to implement the desired electrical function. Depending on configuration, the unit may ship with no internal contacts or paired with a contact block such as 1 NO-1 NC for a standard two-position switch operation. The 800T-H48 is rated for use in environments covered by NEMA 4 and 13 enclosures, making it suitable for wet, dusty, or harsh factory settings. In practice, technicians install this switch in control panels to provide a robust two-position input for machinery, packaging lines, conveyors, and other automation equipment, selecting the appropriate contact arrangement to suit the application. This model is part of Allen-Bradley’s 800T line, which supports modular assembly with compatible 30 mm contact blocks and mounting accessories for a compact control-station solution.
