⚠️ Functional Safety

This 3-position handle switch is designed for low-voltage circuits up to 5 A @ 12–14 V DC (lighting, starter relay, horn, auxiliary).
• Use an in-line fuse rated 5 A max.
• Follow the supplied wiring diagram and tighten the M3 screws to 0.8 N·m (7 lbf-in).
• After first 50 mi / 80 km, re-check all fasteners.
Improper wiring or over-current can cause loss of lighting or engine controls, leading to serious injury.

⚠️ Moisture & Corrosion

The switch body is not sealed; exposure to rain, pressure wash or heavy humidity may cause corrosion and intermittent contact.

To maximise service life:

1. Apply a thin film of dielectric grease to the terminals.

2. Use heat-shrink tubing or a waterproof connector on every joint.

3. Store the motorcycle under cover when not in use.

This part is offered for custom / off-highway applications. Check your state and local regulations before installing on a street-registered motorcycle.

User Manual

This manual applies only to REMMOTORCYCLE switches. It contains important safety and handling instructions. Please read all instructions carefully, especially the safety guidelines, before using the switch unit on your vehicle. Failure to follow this manual may cause damage to the vehicle, compromise road safety, or result in accidents.

Be sure to keep this manual for future reference. If you pass on the switch unit to another person, make sure to also hand over this manual.

Safety

Proper Use

The specifications of the push-buttons:

250VAC 3A - IP45

The specifications of the switches:

0.5 A 50V DC; Contact resistance: 30mΩ Max, Insulation resistance: 100 mΩ Min at 500V DC; Dielectric strength: AC 500V for 1 min

The switches are universal. Mounting compatibility depends on the handlebar and other electronic components.

Using Relays

REMMOTORCYCLE switches are equipped with push-buttons and switches rated for relatively low currents (maximum 3A at 250V for push-buttons and 0.5 A at 50V DC for switches).
They are not designed to directly handle high electrical loads, such as those from a headlight, fuel pump, loud horn, or other high-consumption accessories.

Directly connecting a high load without a relay may:

• Prematurely destroy the push-button or switch (burnt or stuck contacts).

• Cause malfunction or total failure of the electrical equipment.

• Create a short circuit, with fire risks.

Important Points:

• Use a relay suited to the device's power (e.g., 12V 30A relay for an H4 headlight).

• Protect each circuit with an appropriately rated fuse.

• Follow wiring standards to prevent overheating or malfunction (wire gauge, connection quality).

Safety Instructions

This product presents a danger to children and individuals with reduced physical, sensory, or mental capacities (e.g., partially disabled people or elderly individuals with impaired abilities), or those lacking the required experience or knowledge (e.g., older children).

Keep the packaging film and small parts that come with the product out of reach of children. Risk of suffocation.

Risk of Short Circuit

Electrical installation and mechanical mounting on the vehicle must be performed correctly. Improper mounting may cause short circuits or failures in the vehicle's electrical system.

During installation, strictly follow the vehicle owner's manual or a suitable repair/maintenance manual, the manufacturer's specifications, and the control module's user manual.

Always disconnect the vehicle battery before working on the electrical system.

Never apply tension to electrical wires, even when the handlebars are fully turned. Route the wires safely to avoid pinching, abrasion, or kinking.

Risk of Injury

During assembly, ensure the vehicle is perfectly stable and the work area is well-lit.

Installation

Preparation

Lift the vehicle securely (using a paddock stand or center stand) in a clean, well-lit area. The battery must be disconnected before starting (disconnect the negative terminal).

Installation

1. Remove the grips, throttle sleeve, and old switch housings.
2. Loosen the two M3 screws on the switch. The two parts should remain connected.
3. Slide the switches into place. (Remove the internal rings for 25 mm / 1" handlebars).
4. Tighten the M3 screws on the back of the switch housings.
5. Connect the wires to the motorcycle's wiring harness using the diagrams shown at the top of this page.

Risk of short circuit!

Connect the switch unit according to the appropriate wiring diagram, as well as the diagram for the electronic button control module. Be sure to follow the assembly instructions of the electronic control module carefully. Assign the positive and negative terminals according to the specified function in the diagram.

Once the wires are connected, reconnect the previously disconnected battery. You can now test the vehicle’s electrical functions.

Storage

Store the unused switch unit in its original packaging in a closed space protected from moisture and weather.

Cleaning and Maintenance

Clean the switch unit with warm soapy water or motorcycle cleaner and a soft cloth. Never use products that may damage aluminum.

Sunlight & Anodizing

Prolonged exposure to sunlight (outdoor storage) may affect the color of the switch housing.
