Send power betwwen to moving parts?

[Archangel]

Hey Guys

Long time since I wrote for the last time here, I don't have much time free lately I'm afraid.

Well, short question, I need to send 5 volts between two moving parts, like the famous "propeller clock" or like in a slot car.

What I'm trying to find is some nice rigid contacts to attach to a PCB, so they can slide over another PCB to transfer the 5 volts.

Like this: . . .


Hope it's clear what I'm trying to do. Any ideas or suggestions?

Thanks!

Daniel.

Hi Daniel,
Since your application is low power, I E Not several tens of amps, You might consider carbon brushes, I think Home Depot may sell them or LOWES as general purpose replacements for motors. A split ring commutator can be fashioned from copper tubing and epoxy and bruch holders from brass tubing and pc board.
