In my attempt to replace the original switch with what I thought would work my result is a tripped breaker. The original switch did not have a ground and I did not add one to this switch. The new switch says load and line So is the red the load or line?

Your going to have to trace wiring back & see what is coming from the supply cord and what is going to the motor after that it should be easy.

Both cords go into the machine and I can pull them out and see which is which. Now, why is it when I connect them to the switch it trips the breaker. when the slide inside the switch makes contact the black is meeting the black and the red is touching red.

are you sure the switch is not faulty?
show a pic or explain how you wired it up

well i found the problem. I removed the back of the new switch and looked at the configuration of the contacts. After comparing with the old switch I saw they are opposites. So by fastening the wires to the new switch based on the old switch what I was doing, when energized, was connecting black to red and thus tripping the breaker. The bars that energize or take the power from one side of the switch to the other side are different in the switches. Make sense?

yup
glad you figured it out!
