Step 7Attach switch assemblies to motor/battery assembly
At this point you should have:
In order for either switch to turn on the motor, instead of both, we'll attach the switches in parallel. This basically means to treat them as one switch, attaching corresponding thread tails from each strip to the same place.
The motor/battery assembly has two remaining terminals or wires. We'll attach a pair of threads to each of these, one pair to the remaining battery terminal and one pair to the remaining motor terminal.
Attachment technique varies with what the terminals are like. If you have wire, strip as much as you reasonably can, then fold a loop back on itself, knot the conductive thread around the loop, and twist the loop around itself again.
If you have a snap terminal, wrap the conductive thread around it several times and tie a knot.
If you have a tab with a hole, thread the conductive thread through the hole and tie a knot.
Test! Put batteries into your holder and squeeze each of the switches in turn. If the motor doesn't go on, you have a loose connection somewhere. If it went on as soon as the batteries were in, you have a short circuit. If it went on after you pressed the switch and stayed on after you let go, the switch is bad. There are several ways it can be bad - glue not dry, hole too big, hole too small, conductive fabric strips touching outside the switch, etc. If it's not obvious what's wrong, simply make another switch.
Once you've verified the connections, hot glue each knot for stability. Keep tension on the thread as you glue. Test again just to be sure. You can leave the batteries in this time, as the innards of the pillow are done!
- the front & back of the pillow
- the motor & battery assembly, glued together, with one lead connected
- two fabric switch assemblies, with long threads off the ends opposite the switches
