7 World Record

Spencer Lisenby is a pyronary in the world of Dynamic Soaring. We are proud to announce that the last 7 world record DS speeds he has made, have been made using Zepsus Magnetic Switch – the 15A switch now up to 564mph! Also the 7A switch has been used in Spencer’s smaller 2m model up to 524mph…

Spencer Lisenby own statement
For 10+ years now, I have used Zepsus magnetic switches exclusively in all of my models including the 2m Kinetic DP, the world record holding Transonic DP, and also now in the latest Swept Wing Transonic DP. The ability to cycle power without having an exposed switch or having to remove the wing from the model is a huge benefit in the windy, dusty environment where Dynamic Soaring usually takes place. In this type of use, traditional mechanical switches have a track record of failure from dust intrusion. Our high G environment (120+G) is also a cause for concern with mechanical switches that might inadvertently be turned off from inertial forces. I even use Zepsus switches now in simple foam combat gliders to prevent switches from being turned off mid-flight from contact with other models. I have never had a failure or any issue with a Zepsus switch at all. Hard to beat that track record! Thanks for creating such a great product! Keep up the good work!

The new drive train switch is online!

Now it’s here. This journey started 8 months ago. We’ve noticed that many of you have been utilizing the 15A magnetic switch as a drive train switch – a truly innovative adaptation.

The feedback and client usage patterns, serve as inspiration for us, so we started working with your idea and developed something even more powerful to handle higher loads!

We are thrilled to introduce our newly designed version which can now handle up to 25A and withstand up to 20 volts. Now, isn’t that an upgrade? This new model retains all the great features of its predecessor while packing some extra punch!

We appreciate your loyalty and creativity in finding new ways of using our products. Please keep sharing your wonderful ideas with us. They help shape our innovation pipeline. And do give our upgraded switch a great welcome. We’re sure it’ll make your project perform even better.

Happy experimenting with the new improved switche!

The smallest and strongest magnetic switch to date

We am thrilled to share some exciting news with you – we have developed our smallest yet most robust switch ever! It’s so compact, yet incredibly powerful.

This device not only bears our reliable brand name but takes it up a notch as it can handle an impressive 25A and is suitable for up to 4S lipo. This speaks about its efficiency and reliability.

To make things even better, the magnetic switch will be ready for sale come November! You’ll be able to purchase this small but mighty switch in just a few short weeks. Mark your calendar because this is one innovation you surely wouldn’t want to miss out on!

We’re beyond proud of our team that has worked on creating what we believe is a game-changer in the industry. We hope that when you get your hands on one of these magnetic switches, you’ll feel the same way too.

Stay tuned for more updates regarding pricing and availability details closer to launch date.

Thank you for being part of our journey thus far. As always, please don’t hesitate to reach out if there are any questions or if there’s anything else we can assist with.

Magnetic Keychain

There is news from our product development. This time it is a Magnetic Keychain for all those who want the strong magnet, but do not want to have it sitting by the belt. Designed with a large keychain so you have a greater chance of finding it again if you drop it. Made from good materials. It can withstand wind and weather, and will last many years.

Coming up soon – Magnetic Switch 45A HV

Capable of working with 7S Lipo and 45A and 90A peak. It’s designed with XT60 connectors at both ends and new on/off funktion, which provides a more intuitive on/off function. Place the magnet over the switch and wait a few seconds and it will turn on. Repeat to turn off again. It can be used as a power switch for the entire model including the driveline. The technology is the same safe and reliable technology with built-in failsafe function, ultra low stand-by consumption, like all our other product.

General purpose main power switch

Coming up soon – Double Magnetic Switch

Designed for RC jet planes and other double battery models. It’s designed with 2 parallel switches which are activated from one single point. Instead of turning on the ECU in one place and receiver in another. All is located in one place with the Double Magnetic Switch.

The batteries are separate so it is possible to use 3s on one switch and 2s on the other switch. It can be used as mentioned before for receiver and ECU. But also as a switch for a dual battery power unit, receiver and scale light or receiver and smoke unit etc.

The technology is of course the same safe and reliable technology with built-in failsafe function, ultra low stand-by consumption, and clean and easy on-off function, like all our other products.

Double Magnetic Switch

Designed for RC Sailboads

We are working on a new version of our popular magnetic switch. It is designed specifically for RC Sailboads. We have had several requests for a water repellent switch. Below is our first prototype. I am very satisfied with the result so far. Testing is already starting, more will come in order to ensure a good and reliable product.

Magnetic BEC 7A – F5B Flight Test

F5B test

Piermario Cavaggioni and his team mate have complete all test in the workshop. And they have move on to inflight test. Piermario have made a detailed worksheet with data from two test flights. If you are interested, the worksheet can be downloaded here F5B_flight_test_ZEPSUS

I have been contacted by several interested who want more technical details on the Magnetic BEC 7A. For those who can not wait, here are a few headlines.
Input voltage: Designed for 2s Lipo/Liion/LiFe
Output voltage: 5.7V
Output current continuous: 1.75A if used with 2S lipo (7.4V)
Output current burst: >10A if used with 2S lipo (7.4V)
Dimensions including heat shrink: 40 x 15 x 5mm

New Magnetic BEC 7A


There has been an increasing demand for small form factor equipment in new competition planes. It’s one of the reasons why we, in cooperation with the Italian F5B team, have made this new medium size Magnetic BEC 7A. In terms of output power level it’s between the two well-known versions Magnetic BEC 14A and Magnetic BEC 5A. Piermario, my team contact, to the right and Alex his friend to the left, will the next few months test the new version of magnetic BEC. If everything goes as expected, they will be put on the webshop this spring.

The output voltage of the New Magnetic BEC 7A is 5,7V to minimize power loss and increase output power. The wires are upgradet from 0.25mm2 to 0.5mm2, same high-quality wires as the Magnetic Switch 7A.
