Key Features

• CNC Machined Aircraft Aluminium Housing — Manufactured from a solid billet of aircraft-grade aluminium alloy, the switch body is CNC machined to precise tolerances, delivering exceptional strength and longevity that will withstand years of intensive RC use without damage or degradation.
• 8.4V Rated with LiPo Compatibility — Designed to handle 8.4V systems and fully compatible with LiPo battery technology, this switch provides safe, reliable power control for modern electric RC models without voltage-related failures or compatibility issues.
• Military-Specification Toggle Switch — Features a premium military-grade toggle mechanism that delivers positive, tactile switching feedback with no ambiguity about on/off status, ensuring you always know the power state of your RC model at a glance.
• Heavy-Duty Silicon Cable with Quality Terminations — The switch utilises heavy-duty silicon wire throughout, finely soldered and crimped to exacting standards, eliminating poor connections and ensuring stable power delivery under all operating conditions.
• JR-Style Universal Plug Connector — Equipped with a JR-style universal plug (also known as Spektrum/Futaba compatible), this switch connects seamlessly to most modern RC receivers, making it the ideal choice for UK RC enthusiasts running these popular radio systems.
• Integrated Charge Socket — An integrated charge socket is included for convenient battery charging and maintenance without disconnecting the switch leads, streamlining your pre-flight or pre-race preparation routine.
• Brushed Natural Silver Finish — The professional brushed natural silver colour finish provides an aesthetically pleasing appearance that looks at home in any serious RC installation, from competition vehicles to weekend bashers.
• Compact Dimensions — At just 45mm x 25mm x 25mm, the switch is compact enough to fit into tight receiver compartments whilst remaining large enough to operate comfortably with gloved hands in cold weather or high-stress racing scenarios.

Technical Performance

The Etronix Power Switch with JR Plug represents engineering excellence in RC power management. The choice of aircraft-grade aluminium alloy as the housing material ensures exceptional strength-to-weight ratio and superior heat dissipation, critical factors when switching high currents common in modern brushless RC systems. The CNC machining process delivers tolerances tight enough to ensure the toggle mechanism operates with precise, positive engagement every single time—there's no vagueness or hesitation when switching power on or off. The 8.4V rating is specifically chosen to accommodate dual 4.2V LiPo cells (the most common configuration in electric RC cars and trucks across the UK), whilst the internal construction is robust enough to handle the transient spikes and demands of brushless motor systems. The 22AWG silicon cable provides excellent current-carrying capacity with superior heat resistance compared to standard PVC cable, meaning the switch remains cool even during extended high-current operations. Every solder joint and crimp termination has been hand-finished to ensure mechanical reliability; this isn't mass-production assembly but rather professional-grade workmanship. The military-specification toggle switch itself is rated for hundreds of thousands of cycles, meaning you could operate this switch daily for years without mechanical wear or failure. The brushed aluminium finish not only looks professional but also provides natural oxidation resistance that protects against corrosion in humid UK weather conditions.

What's in the Box

• 1 x Military grade toggle switch (integrated into the housing)
• 1 x Integrated charge socket
• 2 x 22AWG silicon wire with universal Spektrum/Futaba JR-style plug connector

Frequently Asked Questions

• Is the Etronix Power Switch with JR Plug suitable for all types of RC models? — Yes, this switch is suitable for any electric RC model using a JR-style receiver connector, including RC cars, trucks, buggies, crawlers and electric RC aircraft. It is specifically designed for 8.4V LiPo systems, which is the standard voltage for most modern RC receivers. However, always confirm your receiver uses a JR-style plug before purchasing.
• What battery voltage does this switch support? — The switch is rated for 8.4V systems and is fully LiPo compatible. This matches the voltage output of two 4.2V LiPo cells in series, which is the most common receiver battery configuration in UK RC hobby shops. Do not use with higher voltage systems.
• Is this switch suitable for beginners to RC? — Yes, the Etronix Power Switch is suitable for both beginners and experienced RC enthusiasts. Beginners will appreciate the simple, intuitive toggle operation and integrated charge socket that simplifies battery management. Experienced racers and bashers will appreciate the military-grade build quality and reliability under demanding conditions.
• What are the exact dimensions of the switch? — The switch measures 45mm in length, 25mm in width, and 25mm in height, making it compact enough to fit into most receiver compartments on modern RC cars, trucks and aircraft whilst remaining large enough to operate comfortably.
• What is the difference between this model and other Etronix power switches? — The ET0770-1 features a JR-style plug, making it ideal for Spektrum and Futaba receivers. Etronix also produces variants with Deans connectors (ET0770-2) and models with integrated fuel dots for petrol and glow fuel compatibility (ET0770-3 and ET0770-4), though these additional features are not included on this base model.
• Is the switch waterproof? — Whilst the aircraft aluminium housing provides excellent weather resistance, this switch is not rated as fully waterproof. It is designed to operate in typical UK weather conditions and withstand splashes and humid environments, but should not be submerged or operated in heavy rain.
• Can I use this switch with non-Spektrum receivers? — The JR-style plug (also called universal plug) is compatible with most modern RC receivers that use this connector standard, including those from Spektrum, Futaba, and many other manufacturers. Check your receiver documentation to confirm JR-style plug compatibility before purchasing.
• What makes the military-specification toggle switch different? — Military-grade toggle switches are manufactured to higher standards than commercial alternatives, with more durable internal mechanisms, positive detent action, and a rated lifespan of hundreds of thousands of switching cycles. This means the switch will remain reliable and responsive throughout years of RC use.
