ETRONIX Switches

Etronix Futaba Switch

Etronix Jr Switch

The Etronix power switch is a tiny MCU controlled on/off switch perfect for your r/c car. A simple push button operates the switch eliminating the problems associated with an ordinary mechanical switch and intermittent contact. The sealed unit is plastic and can easily be mounted to the transponder mount of your model or anywhere else you can mount it using double side tape. The switch also features a LiPo mode and by turning this on the switch unit will auto detect low LiPo voltage and cut off power to protect your LiPo from over dis-charging. This of course can be turned off if you have other safeguards in place or using Life/NiMH/NiCad battery. The switch can also indicate the remaining capacity within your battery via LED indicators.

Please note:- This is for NITRO powered vehicles only

The Etronix Universal Electronic Magnetic Switch is a compact, high-current solution designed for reliable power control across a wide range of RC and electronic applications. Using contactless magnetic switching, it removes mechanical wear points and ensures long-term dependability.

With a 3.5V–13V input range, it’s suitable for most battery setups. The switch delivers a constant 15A output at 25°C, with >burst capability up to 45A (0.1 sec) for handling high-demand loads.

Built for efficiency, it features an ultra-low dropout voltage of 60mV at 20A and standby current below 10µA, helping reduce power loss and extend battery life.

This version is supplied with 170mm 14AWG heavy-duty wire and no connectors fitted, giving maximum flexibility for custom installs and higher current setups. The compact 25 x 10mm module can be mounted neatly inside receiver boxes or sealed enclosures to keep it protected from dirt, fuel, and water.

Why Use a Magnetic Switch?

Magnetic switching removes the hassle of traditional on/off methods. No more unplugging batteries or opening sealed compartments—just switch your model on or off externally using the supplied magnet.

It’s especially useful for sealed or waterproof setups, allowing you to prepare your model in advance and leave it ready to run, with virtually no battery drain while idle. Widely used in boats, gliders, and race models, it’s a simple upgrade that makes day-to-day use much easier.
