Help wiring toggle switch

[ALExanderH]

Hi, I have this toggle switch that I'm going to use with my PID controller.
I don't have any instructions with it so I'm lost in how to wire it.
There are markings on the side with numbers which I put on the attached photo.
Any help?

Cheers!

Looks like a DPST (double pole single throw) switch. When in the "On" position, terminal 1 will be connected to 1A, and 2 will be connected to 2A. In the "Off" position, none of the terminals will be connected to any other terminal. You can check this with an ohmmeter.
