I need to get a 110v supply from a wall, through a door frame and into the glass rebate of a door..
Has anybody successfully done this?
I want it to be concealed so the little boxes with flexible conduit are no good.
I’m thinking of using power transfer hinges.
It’s to power smart glass in the door..
The windows are easy enough as they are all stationary.

there are loads of spring contacts out there but not suitable for 110v
you could transform 110 down to 30 outside the frame and then step back up inside the door but its a messy solution and the current at 30v might be higher than the contacts are rated at.

Not got much room to play with inside the glass rebates..
The glass comes with 2 thin tails which I will twist,solder & heat shrink onto the supply legs..
The load is about 10 watts..
The other option I was thinking of was how to concertina the wires up in the frame rebate when the door closes
