My husband making an electronic toy that plugs in, will he burn down house? Is he using the right thing?
His plan is to use reed switches and magnets. put the magnets in the pieces and they will activate the closed reed switch. He wants to link 8 of them together to complete the circuit, so there will be 8 pieces to put in place. He wants to have the switches (which look like little tubes) in the box and a magnet in the piece.
Will this work? Is he going to burn down the house? Any suggestions?
