I want to put some LED lights on my sliding gate. I wondered if I could
power them inductively, with a power 'transmitter' fixed to the gatepost

the lights is 24W at 12VDC. The positional accuracy of the gate is good.

Use low voltage and just use bare contacts. Rubbing ones make them self cleaning. As on tail lights of some cars. Or "lift off" electric kettles.
