Frequently Asked Questions

• Is the Etronix Jr Switch ET0780 suitable for beginners? — Absolutely. This is one of the simplest RC components you can use. There's no programming, no setup, and no complex electronics to understand. Simply plug it between your battery and receiver, and you have on/off control. It's perfect for newcomers to the RC hobby who want straightforward functionality without any learning curve.
• What does the JR plug connector mean? — The JR connector is the industry-standard plug format used by most RC receivers, servos and battery packs in electric RC cars, planes and boats. If your receiver has a JR-format power port, this switch will connect directly. This is by far the most common connector format in the RC hobby, making JR switches universally useful.
• Why would I need a separate switch if my RC model already has one built in? — Many RC models use tired or worn receiver switches that can fail over time. Having a spare Etronix Jr Switch allows you to replace a faulty switch quickly and inexpensively, keeping your model operational without lengthy repairs. Additionally, some RC enthusiasts use external switches for easier access and control, particularly on larger models where internal switches are hard to reach.
• How does this mechanical switch compare to electronic power switches? — This mechanical switch is simpler and more reliable than electronic alternatives because it has no circuits, no microcontroller and no MOSFET components that could fail. It also provides zero voltage drop to your receiver and servos, whereas electronic switches with intelligent features do create a small voltage loss. For basic on/off control, mechanical switches are the most straightforward and dependable solution.
• Is the Etronix Jr Switch ET0780 waterproof? — This is a mechanical switch designed for standard indoor and outdoor RC use. For boats and waterproof applications, you may wish to consider sealed or waterproof electronic switch options. However, for dry-land RC cars, planes and standard outdoor use, this switch performs reliably in typical British weather conditions.
• Can I use this switch with any battery type? — The Etronix Jr Switch works with any battery pack featuring a JR connector, including NiMH packs, LiPo batteries, and LiFe batteries across all voltage ratings commonly used in RC vehicles. Simply plug your battery into the switch, and plug the switch into your receiver.
