Can I use a standard kill switch from the free market on my wheel base?

Yes, you can can use a standard kill switch for all Wheel Bases (which do not feature one as accessory, such as CSL DD, CS DD and others) for safety reasons. Those switches can physically disconnect your wheel base from the power surge in an emergency situation.

Please do not use such a switch in normal usage circumstances to simply power off the device. This may negatively impact the functionality or even harm the device!
