Waterproof Toggle Switch BERM Series — Reliable Panel Control for Car, Boat & Industrial Use

Whether you're wiring a custom boat dashboard, building a 4x4 accessory panel, or replacing a failed switch on an RV, finding a waterproof toggle switch that fits your circuit — the right pin count, the right throw, the right action — can eat up hours of searching. These BERM series waterproof toggle switches are stocked for automotive electricians, marine builders, DIY fabricators, and hobbyists who need a dependable panel-mount switch without guesswork.

Each order includes your chosen BERM model switch (available individually or in packs of 3, 5, or 10) plus an optional waterproof rubber boot cap for full actuator protection. The switches feature a metal threaded bushing body for secure panel mounting, with configurations spanning 2-pin to 6-pin and 2-position (ON/OFF) to 3-position (ON/OFF/ON). Both latching (maintained) and momentary action types are available. The panel cutout is typically 12mm (≈15/32") in diameter. Rated at 15A / 250V AC, these switches are also suitable for 12V and 24V DC automotive and marine circuits.

Typical applications include accessory switch panels in trucks, Jeeps, and off-road vehicles; navigation light and bilge pump controls on boats and marine consoles; fan, pump, and relay control in RV and camper van builds; and industrial control boxes requiring a rugged, splash-resistant toggle switch. Long-tail searches like "waterproof toggle switch 12V car panel" and "ON OFF ON toggle switch 6 pin boat" describe exactly what this listing covers.

🔌 Compatibility Note: Standard threaded bushing mount — typically 12mm (≈15/32") panel cutout. Compatible with 12V / 24V DC automotive and marine systems, and rated for 15A / 250V AC. Select your model, pin/position configuration, and latching or momentary action from the dropdowns above.

✅ Key Features of These Waterproof Toggle Switches

💧Waterproof & Splash-Resistant Body — The sealed switch body resists moisture, making it suitable for boat dashboards, outdoor panels, and engine bays where exposure to water and humidity is unavoidable.
⚡15A / 250V AC Rating — Handles demanding loads including lights, fans, pumps, and relays in both AC and DC circuits (12V / 24V automotive and marine systems), giving you headroom for real-world accessory wiring.
🔀Latching & Momentary Options — Choose latching (maintained ON/OFF) for power circuits and lights, or momentary (spring-return) for horns, starters, and pulse-triggered relays — both available in the same listing.
📐2 to 6 Pin Configurations — Covers SPST (2-pin), SPDT (3-pin), DPST (4-pin), and DPDT (6-pin) wiring needs, with 2-position ON/OFF and 3-position ON/OFF/ON throw options for versatile circuit control.
🔩Threaded Bushing Panel Mount — The metal threaded body passes through a standard panel cutout and locks with a nut, providing a secure, vibration-resistant installation in automotive dashboards, marine consoles, and control boxes.
🛡️Optional Waterproof Rubber Boot Cap — Add the Waterproof Switch Cap variant to protect the toggle actuator from direct water spray, dust, and accidental activation — ideal for open cockpit boats and off-road builds.

⚠️ Installation Note: Always verify the switch current rating against your circuit load before installation. Use an inline fuse rated for your load. For DC applications, current ratings may differ from the AC specification — contact us to confirm for your specific use case.

❓ Frequently Asked Questions

How do I choose the right pin count and position for my application?

The number of positions refers to how many switching states the toggle has: 2-position is ON/OFF, 3-position is ON/OFF/ON. The pin count reflects the circuit configuration — 2-pin for SPST (single-pole single-throw), 3-pin for SPDT (single-pole double-throw), 4-pin for DPST, and 6-pin for DPDT (double-pole double-throw). Match the pin count to your wiring diagram. If you're unsure, contact us with your circuit requirements.

What is the difference between latching and momentary toggle switches?

A latching (maintained) toggle switch stays in the position you flip it to — ON stays ON until you flip it back. A momentary toggle switch only activates while you hold it; it springs back to its default position when released. Latching is used for lights, fans, and power circuits. Momentary is used for horns, starter buttons, and pulse-triggered circuits.

What current and voltage can these toggle switches handle?

These BERM series switches are generally rated for 15A at 250V AC. For DC applications (such as automotive 12V or 24V systems), the current rating is typically derated. Always verify the load current against the switch rating before installation, and use an appropriately rated fuse in the circuit.

Are these switches waterproof enough for boat or outdoor panel use?

The switch body is sealed and water-resistant, suitable for splash-prone environments like boat dashboards, marine consoles, and outdoor enclosures. For full actuator waterproofing, add the optional Waterproof Switch Cap (rubber boot) variant. For heavy spray, also seal the panel cutout with a gasket.

What panel cutout size do these switches require?

BERM series toggle switches typically require a round panel cutout of approximately 12mm (≈15/32") in diameter. The switch body threads through the hole and is secured with a nut from the back. Contact us to confirm the exact cutout dimension for your chosen model before drilling.

How do I wire a 3-position ON/OFF/ON toggle switch?

For a 3-pin SPDT 3-position switch: the center pin is the common (COM), one outer pin is output A (activated in position 1), and the other outer pin is output B (activated in position 3). The center/off position disconnects both outputs. For 6-pin DPDT models, the same logic applies to two independent poles simultaneously. Always refer to a wiring diagram specific to your application.

Can I use these switches in a 12V automotive or RV electrical system?

Yes — these toggle switches are commonly used in 12V and 24V DC automotive, RV, and marine electrical systems for controlling lights, fans, pumps, and accessories. Use spade terminals or solder connections at the switch terminals, and always protect the circuit with an inline fuse rated for your load.
