Transmission Switch Identification

[McGruff44]

I am rebuilding my 78 FJ40 4 Speed transmission. There are two switches on the top of the transmission. One I know is a Backup Light switch. I need help identifying the other. I'm looking for a replacement switch but cant find any reference to what the switch is or where I can get another.
Thank you for your help.

Is it one of these gear boxes?

Emissions switch. Unless you're keeping your emissions, you don't need it.
