This experiment used two SPST switches. SPST stands for single pole single throw switch. This is just one of the many different types of switches out there.
When you flip (or throw) the pole on the toggle switch, it makes a connection with one of the contacts inside. In an ON-OFF switch one direction will make a connection with a contact allowing the electricity to flow through the circuit. The other direction will make no connection to any contact, thus not allowing any electricity to flow through. An ON-ON switch makes a connection with a contact in either direction.
Single throw means there is only one pole making connections with contacts. Different from double throw in which the switch is flipping two poles.
Making some switches:
I only ordered one ON-OFF-ON switch cause it was the cheapest, the difference here was I had to hold the switch in the on position, annoying but doable.
Using those cute little alligator clips again I was able to hook up the circuit as directed by the book. The LED decided it wanted to work for me today and lit up.
RESULTS: it works
