The Wirthco 20505 is a battery doctor 2-position on/off plastic toggle.
Key features
- On/Off Circuit Control - 2: position plastic toggle switch delivers straightforward on/off control for 12 Volt accessories, lights, pumps, and auxiliary circuits in vehicles, boats, RVs, and DIY electrical builds.
- 20 Amp 12 Volt Rating: Rated 20 Amps at 12 Volts, sized for lighter-duty switching tasks where a compact panel switch is preferred over a heavy-duty disconnect.
- 1/4 Inch Blade Terminals: Standard 1/4 inch blade terminals accept common female spade connectors, making wire-up quick with crimp-on terminals already used in 12V wiring.
- 1/2 Inch Panel Mount: Requires a 1/2 inch mounting hole and ships with a nut and back-up collar so the switch can be secured cleanly into a dash, console, or custom switch panel.
- Compact Plastic Housing: Lightweight plastic toggle body keeps the switch easy to mount in tight panel locations while keeping a familiar lever feel for quick on/off operation.
Before you order
- Check the group size, terminal layout and cold-cranking amps against your current battery.
- Compare the connector and the part number on your old part before ordering.
