Relays are used where it is necessary to control a circuit by a low-power signal with complete electrical isolation between control and controlled circuits, or where several circuits must be controlled by one signal.

Just standard SPST Switches are needed for this application.

Can you dumb that down just a bit?

A relay is a switch. (basically) I do not use the word relay very often because most everyday people do not understand relay. I do not have a need to make other people feel dumb so I use laymens terms as much as possible. But you asked.

SPST = Single Pole Single Throw - AKA - Toggle switch

I used to know the SPST term, It has been a while and I didn't recognize it. I get the concept myself, but I was thinking it would be helpful to those who know absolutely nothing about electronics. That should help, thanks!

My Dad would shoot me...he used to be an electrician.
