I don't see them on the switch just on the wires

I have a frigidaire dryer I took apart to fix the glides. I did not pay attention to the wiring .any help

You will have to wire it with a meter. You have a common coming in and with the door open power comes in the common and goes to the light (Normally closed) then with switch depressed it energizes dryer circuit in series with the safeties (normally open contact). It's that simple. I will give you a link to download the manuals here, but use a meter to verify: https://dl.dropboxusercontent.com/u/...e%20Manual.pdf

Any time you work on an appliance you should have a meter handy and know how to use it. It's very easy to use a meter and it will answer all questions about what is wrong if used correctly. You will not have to guess; you will know.
