Ultra Reliable Switch Test with EDF motor

Hi Guys,

I just released an Ultra Reliable Switch for RC.

Maybe you know, i'm designing FPV electronics but this product not for FPV :)

We are sharing same flight field with gliders,glow and electric planes and most important problems was switches for everyone.

This is why we designed this small circuits

Ultra Reliable Switch 20A Current Test from Melih Karakelle on Vimeo.

Standard slider type switches are the most important crash reason on glow planes/gliders and they can affect from vibration, dust, oil and moisture.

Ultra Reliable Switch works when only slider switch mechanical off, and you are forcing to close it when switch on. This electronic design uses high power MOSFET for opening the switch and current limit is extremely higher than all mechanical switches.

We are using 20Ah MOSFETs for this small switches and they can handle 100Ah peak currents on hard conditions.

You can use it with your Gliders, Glow planes or Small EP planes.

Features

Low Quiescent Current (50uA on 5Volt)
Very Low Internal Resistance (0.006 Ohm on 5V)
Wide Operation Voltage (2-30Volt)
Very High Current Resistance (20A Continuous, 100A Pulsed)
Onboard LED indicator
Large Soldering Pads

Usages

Receiver battery switching for Glow and Gliders
Ignition system switch for Fuel Engines
LiPO switch for small EP planes (20A Max)
Safe Switch for other hobby electronics

@Sgt Ric
I'm planning higher amper versions but not in short term, This version useful for replacing receiver switches, maybe 50Ah version will useful for switching LiPO batteries :)

It appears this is a slide ON/OFF (2 position) switch. As it's not momentary (i.e. button) I wouldn't think a debounce is needed. Case-in-point, typical slider ON/OFF switches for power systems do not include a debounce. This circuit is no different... aside from the fact that ON is OFF and OFF is ON. :)

Is there a de-bounce circuit for slide switch?

He is very clever man ! who keeps you...

Anything planned for higher amp systems?

At first (before reading comments) I thought this was ridiculous, since it uses a slide switch to control the mosfets. But after reading, I think it's brilliant!! Of course... it makes perfect sense... allow "normally open" to trigger the mosfets, and you've eliminated most of the problem! Congratulations... a simple, but ingenuous solution.

@Melih
Great, a simple solution to a potentially complex problem .... like it

@DrJeseuss

You are completely right :)
Thanks for this great explanation
DrJeseuss June 7, 2010 at 7:53am

I believe what this does is as follows (only speculation based on reading through): If switch is ON, circuit is OFF meaning the battery, etc is OFF as with a normal switch. Then when this switch is OFF, circuit goes ON applying power. He's stating that a normal switch that's ON can be interrupted to OFF from vibration, but that a normal switch is OFF, vibration can't make it go ON. Thus, this circuit/switch setup would only disconnect power when you change the switch position, not from any other cause.

I'm not agreeing or disagreeing with any of this, simply trying to clarify the purpose.

Very simple, i'm using slider for opening or closing it :)

It closing circuit when slider off
Opening it when slider on

just reverse than normal slider. And this idea increasing reliability 10 times more than normal switch and electronic contact handling 10 times more current than mechanical one.
