About this part

Ruddog Electric Power Switch with Voltage Cutoff. This power switch is a great option to simply and safely control the power from the RX battery in your Nitro RC model. A LiPo cut-off protects your receiver battery, which can be turned off when using NiMH or NiCd batteries. The LED status light allows you to monitor how much capacity is left in your RX pack. Package includes one power switch.

Voltage Range: 4-12V
Maximum Current: 10A
Weight: 7g

Eric LarsenVerified owneron Ruddog Electric Power Switch w/Voltage Cutoff

I can't recommend this switch. I've purchased two now and they are both in a constant "on" state. I guess that's better than them not working at all, but as soon as you plug them in, they just feed power through, regardless of what you do with the button. Two in a row tells me they aren't built well. Edit: welp, I figured it out. Apparently, if you are using this in a unique situation like I am (using as a receiver power switch in an electric model with two ESCs), the switch can be powered through the ESC receiver harness ground. I am powering two ESCs and this switch off a 2s lipo. The receiver power wire from both ESCs has been disabled, but the ground and signal remain connected. This switch powers through the ground circuit, even with the ESCs off. If you disconnect the ESC ground as well, it functions correctly.

Very good power switch have it on 2 of my Nitro builds and never had any issues so far works great!!!

Blaine PlattVerified owneron Ruddog Electric Power Switch w/Voltage Cutoff

I have had no problems with this switch. Put in on my truggy and plugged the battery in and took off. Seems like a good product for what you pay for.

These are great, I have 3 of them. Easy to install and the best way to keep your Lipo safe.

What reviewers say

Three of four reviewers are positive, citing easy installation, reliable operation on nitro and electric builds, and good value. One reviewer reports the switch stayed in a constant on state after plugging in, across two units, regardless of button position. That reviewer later attributed the behaviour to an unusual setup, powering the switch through an ESC receiver harness ground with two ESCs, which suggests the problem may be configuration-specific rather than a defect. The reviews do not state whether the voltage cutoff feature was tested. Overall sentiment is favourable, though the sample is small.

  • + Easy to install
  • + Reliable in use
  • + Good value for price
  • − Stayed on when plugged in (one reviewer, unusual wiring)
