ZB4-BD2
在产Harmony XB4 2-Position Selector Switch Head
2-position maintained selector switch head for Schneider Harmony XB4 series. 22mm cutout, IP66. Standard handle.
常见应用
Two-position selector switch used for mode selection: manual/auto, local/remote, on/off. Common on HVAC control panels (fan speed selection), conveyor systems (forward/reverse), and pump stations (hand/off/auto — though that needs a 3-position variant). The maintained action means it stays in the selected position, giving the operator a visual indication of the current mode. Black handle is standard; keyed variants (ZB4-BG) prevent unauthorized mode changes.
