Selection Notes

The ZB4BK1233 stays in whichever of its 2 positions the operator last selected, unlike the spring-return ZB4BD4/ZB4BJ4 heads, so it fits mode-select functions (auto/manual, local/remote) that must hold their state without the operator keeping a hand on the switch. Fit it with a universal LED contact block matching the control-circuit voltage so the green lens lights to confirm the selected position; an unlit green head (ZB4BD-series) is the right choice instead where no illuminated confirmation is needed.
