I am working on a project , where I need to break the path providing 110V to a motor. What are the different ways of doing it ? I am aware of only two ways :1 ) using a mechanical switch 2) a relay .
Are there any other safe, reliable and possibly cheaper ways of doing this ? May be a solid state solution ??
Ebay is full of cheap solid-state relays that have logic level type inputs, safely isolated. I doubt it's worth making one from scratch, unless for fun.
For a motor start application you need a SSR capable of starting your motor size, and that type of motor.
