ALX-HB4-BK13 Illuminated Three Position Selector | 22mm
22 mm illuminated three 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-BK13 is the three position version of the illuminated selector. Left, centre and right, with the knob lit so the active position is unmistakable. It suits a three-state selection where the operator has to confirm the mode at a glance, such as hand / off / auto on a line that runs unattended between shifts.
