Allen-Bradley 800TC-XD1 Contact Block

Allen-Bradley 800TC-XD1 is a 30 mm shallow contact block designed as an accessory for the 800T and 800H family of pushbuttons, providing a single normally open (1 NO) contact to extend the switch's electrical functionality. Part of the 800T accessories lineup, this block is intended to mate with 30 mm 800T pushbuttons and is wired through finger-safe terminals guarded by the block (FS) for safer panel connections. The official documentation identifies the part as 800TC-XD1 and describes it as a 30 mm contact block for 800T pushbuttons with 1 NO contact; the accompanying datasheet notes the "FS Shallow 1NO Guards On Terminals" configuration. Use it in control panels where a 30 mm pushbutton requires a dedicated normally open contact to drive downstream circuits.
