ALX-HB4-BK12 Illuminated Two Position Selector | 22mm
22 mm illuminated two position selector switch, LED illuminated knob, red / green / yellow / blue, 6-220 V, 1 NO + 1 NC contact, zinc alloy chrome bezel, screw terminals.
The HB4-BK12 combines a two position selector with an illuminated knob: the selected position is shown by the lamp as well as by the knob angle. On a panel with several selectors it removes the guesswork about which mode is active, and it lets a remote operator see the state from a distance.
