This trick involves the use of a light that turns itself on and off like an oscillating switch or switchblade. This works by creating an electric current that keeps the switch or switchblade on or off. A very simple idea that I believe can be understood with the help of some basic math.
Let’s say a switch or switchblade is made up of four contacts. The outer contact on each end is made of steel. One contact (the green contact) is connected to a positive rail on which you can make a voltage with. Then one of the contacts (the yellow contacts) is connected to a ground.
You make a voltage with the green contact and push the switch off of its contacts. A lot of wires go for this effect.
Now you have a light switch that works as a switchback. It’s a very simple idea and can be done with a single pin (the white contact). There are 3 wire connections but you only need to connect the wires together (the red, yellow, and green) to make it work.
The light switch is called an oscillator. We would say that the light switches function as an oscillator. If a light switch were an oscillator, it would generate an electric current that causes the switches to cycle. If a switchback were also an oscillator, it would also generate an electric current that causes the switches to cycle.
A light switch can be created in exactly the same way as an oscillator. A simple way to create a light switch is to use a few simple tools and one battery. I made one of these switches by combining some thin electrical wires with a thin film of zinc oxide. I then used this film as an insulator and some hot glue to glue the wires onto the switch. I used hot glue in case I needed to reuse the old switchback.
Now, I have the same light switch that I originally posted two years ago. The wires now get very hot to touch and I don’t have to re-heat the wires too often. One battery in it won’t last forever either and I also made some buttons that use the battery to create a light switch on the first button. The buttons work fine and look very cool to the end user.
