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.
Tom Chalfant’s Skipjack
I just received an email from Tom with an update from one of his project with the Magnetic Switch 7A Waterproof. One of the attached photos was so beautiful that I just have to share it. Here you may see why I am so fascinated by the picture with Tom’s Skipjack in the water.
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.
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.
Test of Magnetic Switch 7A Waterproof in RC submarine
We have been contacted by Tom Chalfant. He has been building RC models submarines in many years. He offered to test our new product, which is the Magnetic Switch 7A Waterproof. Below you see Tom Chalfant with his Seaview and a Jeff Porteus’ slightly larger version.
As Tom says: These subs run very much like the real subs. There are many different ways we submerge. We have systems that use a piston or pump that will bring in or push out water/air to change the buoyancy enough to submerge (Static diving) and others that use just forward motion to dive (dynamic diving). The electronics are kept in a WTC (Water Tight Container). This area usually stays very dry. The Seaview had an electronic switch, but it is not waterproof or resistant and condensation cause a short. I have been looking for a magenetic switch that would serve our hobby and offer protection like yours.
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.
Dual Battery Magnetic Switch 7A ready for sale.
John Bitzer wrote an email to os with a wish for a switch ready to use in F5J competition gliders. Signal passthrough for Speedcontroller and redundant functionality, were some of the wishes. The final result can be seen below. Light, strong and super reliable.
Where to buy Zepsus Products
New product in the magnetic switch family
Dual Battery Magnetic Switch 20A
Designed for large scale RC gliders, where safety is a key component. Small and super reliable, due to it’s redundant function. Incredible strong, tested with short current burst of more then 200A.
A simple solution is often the best
David has a simple and smart solution for not forgetting the magnet.
Magnetic BEC 7A – F5B Flight 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)
