A 2-position switch toggles between ON and OFF — ideal for simple on/off control of lights, fans, or motors. A 3-position switch adds a center-off or center-on state, which is typically used for reversing motor direction or controlling two separate circuits from one switch. Choose based on how many switching states your application requires.

16mm (≈5/8") refers to the mounting hole diameter required in your panel or enclosure. Before ordering, drill or verify your panel hole is 16mm in diameter. The switch body is generally slightly larger to allow the mounting nut to secure it from behind.

This switch is rated at 20A at 250VAC. For DC applications, the safe operating current is generally lower — typically derate to around 10–15A at 12–24VDC. Always verify your circuit's load requirements before installation.

Yes, this switch features a waterproof design suitable for outdoor enclosures, marine panels, and industrial equipment exposed to moisture or dust. For fully exposed outdoor installations, we recommend mounting it in a weatherproof enclosure for added protection.

Select the LED voltage that matches your indicator circuit voltage, not your load voltage. If your control panel runs on 12V or 24V DC (common in automotive, marine, or low-voltage systems), choose 5-24V. If your panel operates on standard household AC (110V–220V), choose the 220V LED variant.

Chrome Plated Brass offers a polished, corrosion-resistant shell suited for visible panel installations. Black Oxide Metal provides a matte industrial finish with good corrosion resistance, popular in automotive and equipment builds. Socket Wire is the bare switch body with pre-attached wiring leads — ideal when you need to wire directly without a panel-mount shell.

Yes. The waterproof construction and 5-24V LED option make this switch well-suited for 12V and 24V automotive, marine, and RV control panels. The chrome brass and black oxide shell variants are both commonly used in these environments. Ensure your wiring gauge matches the current draw of your load.

Installation generally requires a step drill bit or hole saw to create the 16mm (≈5/8") mounting hole, a wrench or pliers to tighten the mounting nut, and a screwdriver or wire crimper for terminal connections. No special tools beyond standard electrical hand tools are typically needed.
