The KCD4 Rocker Switch is a double-pole, double-throw (DPDT) rocker switch, often with ON-OFF or ON-ON configurations and a built‑in indicator lamp. It has six main terminals arranged in two rows for two separate circuits:
- Middle pair: common inputs (line/hot for each pole).
- Top and bottom pairs: outputs to load(s), depending on switch position.
- Lamp terminals: either separate pins or internally tied to line/neutral.
Wiring basics:
- For ON-OFF: connect power to the middle terminals, loads to one side; the other side unused.
- For ON-ON: connect two outputs per pole.
- Lamp: connect to neutral and line (per datasheet). Always verify pin layout on the specific KCD4 model.
