This is the KO Propo Electrical Switch 2. The popular KO Propo Electrical Switch has been updated, and now features a LiPo low voltage cutoff! Additionally, the CPU powered switch features a push button on off switch that will help to prevent the switch from failing, as well as a 5 LED display that displays the voltage level of the receiver pack.

  • CPU powered electronic push switch (ON / OFF) can prevent a power disconnection caused by momentary overload or loose connectors.
  • 5 LED battery voltage level indicator.
  • LiPo mode function so if the battery voltage falls below 6V, output is cut to prevent over discharge.

This product was added to our catalog on July 15, 2011

Over-priced switch. It works well, but mounting options are limited. I resorted to double sided tape.

Price would be easier to swallow if there was a charge cable as part of the harness.

The battery monitor is nice to have and is supposed to take you down to 6v iirc.

Probably the best switch for the money with a lipo option. I'm using one of these on a life battery as well, no issues thus far.

Great switch. Although either my battery never dies down or the LED indicators are not accurate. Either way, I like the fact I have an external indicator that the switch is on. I'd buy it again.

This switch is so rock solid. It's the only switch you can run in off road if you are going to run a switch at all. I have had 10 of these and every single one has worked flawlessly, not just for a short period of time, but YEARS. I take them out and move them from car to car to car, and they keep working forever. I trust this thing enough to run it at a world level. Looking at the negative reviews, it's pretty obvious operator error.

I currently use it on my Mugen MTX and MRX and both works perfectly. I like the fact that it has an indicator battery level marker so you know when you need to recharge your batteries. With the mugen there is a special area where you can screw this switch onto which makes it perfect as you do not need to double side it to the chassis. So far have been using them for a year without any issues. I only use and trust KO products.

It is a bit big, it's expensive, Its got a silly LiPO cutoff ( I'd rather kill a receiver pack than have a runaway nitro vehicle), Its got a power meter (cool, but not super useful), and it doesn't have a build in charge lead.

***BUT*** it always turns on and off when I want it to. Never turns off or on when I don't want it to. It's simply a great switch, probably the best switch I've used.I've been running one of these for about 6 months. Life in a nitro vehicle is rough on electronics. It still works as good as it did when I took it out of the package, unlike most mechanical switches that are lucky to last 1-2 months. It's worth every cent.

I see quite a few good reviews on this so I'm not understanding why mine is crap right out of the package. I was getting a runaway half way through my 2nd tank and after servo replacements and other tests and a few outings, I discovered it's this switch cutting off my power at 6v but it's hooked up to a Nimh battery.
I contacted KO and he said to check that it's not set on Lipo mode. I checked, it wasn't. This switch is just crap.
Never getting another one and I'm sorry I bought this one.

Was great for two outings. Then, after moving and getting back to the track about a month later, the switch did not want to turn on. The warranty period through KO is 90 days. Yes, I disconnect my LiPo's after every outing.

I guess I've got a nice paperweight as the 90 days was up by my third use.

I've had this for a while now & it's so cool when you turn the power on to actually see how much power the receiver battery has by just tapping the button . I use lipo batteries which are dangerous so the cut-off kicks butt . Tankgyrl

A Must for Rc.. Great item

Would of gave it 5*
But if your live Overseas
Like in Europe ect.. you be paying alot More,because of the Custom cost
So it won't be delivered to your house
It will go straight to your post office
For collection and have to pay the custom
Charge. And that's with any item you purchase From Amain. If u live overseas
My only downfall with this online site
