I have a prop that I altered to run off of an ankle switch. I made a simple holder for the straps to hold the magnet and the switch. These are the tops of an old pair of socks that I cut off.
I simply folded them in half upwards to make a little pocket. Then I sewed them to make the pocket hold the magnet or button. Simple solution, however if I keep the prop running this way, I’m going to make a better version.
