Any tips for my project? read details...?

Question

I'm planning for an electronics project which is a combination lock for an outlet/ac source.. Any tips on how to junction my combination lock prototype to the outlet? or any tips you can give for its improvement ~ highly appreciated.. tnx

Answer 1

Make it purely mechanical, otherwise you won't have a fail-safe situation. Replace the outlet cover, which is attached via one s***w, with something that covers the slots and requires you to turn the combo lock to the correct numbers so that the cover slides back exposing the slots.

By combination lock I assume this is a purely mechanical lock (turn the dial to the correct numbers) anyway, not a keypad type which has electronics.
