Allen-Bradley 800T-N2KG4B is a 30 mm diameter panel-mount selector switch with four operator positions and a maintained (latching) action. In the KG4 configuration it uses two contact blocks for a total of 2 normally open and 2 normally closed contacts (each block provides 1 NO and 1 NC), with termination on terminals and no guards. The operator uses a white insert with a standard knob, with a knob or wing-lever option depending on installation. This 4-position device is commonly used for mode selection, start/stop sequencing, and parameter selection in industrial automation, fitting control panels and machine controls in manufacturing environments.
