This is the ProTek R/C Electronic Switch. The ProTek R/C Electronic Switch is a lightweight and compact MCU controlled digital ON/OFF switch for your radio controlled model. With the push of a button this digital electronic switch eliminates the problems with intermittent contact associated with mechanical switches. This ProTek R/C Electronic Switch can be easily mounted to the transponder mount of your model or any other suitable location using double-sided tape (optional bottom covers are included).

The ProTek R/C Electronic Switch includes a LiPo mode that when selected, will auto-detect low LiPo voltage and will cut-off power from your LiPo battery to prevent over discharging. LiPo mode can be turned off if other safeguards are in place or you are using a NiMH or NiCd battery. The ProTek R/C Electronic Switch also monitors the remaining capacity and condition of the battery pack, and indicates the status with the use of LED's.

ProTek RC Electronic Switch w/Voltage Cutoff
The switch is awesome. Been racing with two of them of both vehicles for over a year. Work like new. Zero issues. This review is purely to complain to Amain about the absurd up charge on this product. I got mine for 16 bucks each at vp pro usa. Protek product are good sometimes. But my god a 250% markup? Wtf

ProTek RC Electronic Switch w/Voltage Cutoff
Ok I tried it ! Maybe it's just me or the choices I have made with switches ( on and off buttons ) on ALL of my RC's ! This one didn't last a day of practice ! Running this in a Losi 3.0 with Dyn lipo ! All of a sudden just cutt off - fully charged lipo - all connections brand new. There is NO WAY to run a product that you do not have the confidence in, when you are using when it comes time for the Amain event ! I do not recommend this product or endorse this product! No way to say it was a bad batch because when you buy something you expect it to work flawlessly the first time with out having to work out the BUGS or batch number supplied with it ! Again a day or practice and didn't last ! I do not recommend this product ! Not looking for a refund or store credit - just a product I can rely on !

ProTek RC Electronic Switch w/Voltage Cutoff
Has worked very well for me so far. I've had it for about 4 months. Update: 4/21/16. Switch still works on my nitro buggy and truggy, but noticed case is cracking. I had to ca the switch on the truggy. I have one layer of parma gel tape under it. I may go with two layers. Update 9/6/16. The two layers of parma type tape seems to work.

Mounted this onto my N5c, I have used it for about 6 weeks now. Working as expected and described. I would like to see another version of this switch that can handle the higher amperage of 20 amps
