Holger, if I read you right you are saying that main power must be switchable? Unless you count the link, I have never seen a physical switch for the drive or weapons power on a robot, and I passed the tech check at series 7 without one.

Or are you saying that switching off receiver power must immoblise the robot? That is in both sets of rules, but it wouldnt say such a situation counts as a switch for the main power.
