ABB Busch-Jaeger Basic Unit Installation Switch - 2CKA001012A1168

This cross switch from Busch-Jaeger has one control knob and is used for switching one lamp from 3 different points. The cross switch should be connected to two or more changeover switches for this purpose. Controlling the same lamp from more than two places is very convenient in, for example, stairwells of flats and rooms with three means of access.
