Make-N-Take Battery Device Adapter/Interrupter
A battery device adapter allows a battery operated toy or device to be used with a switch for activation. The adapter slips between one of the batteries and is then plugged into the switch. The individual then presses the switch to activate the toy or device.
1. Cut speaker wire to desired length (9 to 12 inches). Prepare ends by separating and stripping one-forth inch insulation off of wire.
2. Prepare two gold circles/disks. Remove posts and file smooth.
3. Solder the conductors at one end of the wire to the disks - one conductor to each disk. Be sure to bring the plastic insulation right up to the edge of the disk, but not onto it. Try to keep the solder and the wire flush with the disk and close to the edge.
4. Lay two layers of double-stick tape across the "bare" side of one of the disks. Each piece should extend past the edge of the disk and should have no wrinkles.
5. Stick the untaped disk (unsoldered side) onto the taped disk (unsoldered side) so that the wires are aligned (coming off in the same direction). Trim excess tape with scissors leaving a one-sixteenth inch rim all the way around the disks.
6. Slip the jack's plastic cover over the other end of the wire (check cover orientation). Twist wire ends, thread through hole at base of jack and connect conductor wire with solder. Connect the other conductor wire to the other end of jack in the same manner. Screw the plastic cover back into place.
7. Test the interrupter.
