KoP component that acts as a double throw switch

You can get that from the Digital Sidecar or the Camera supply on the PD board.

I guess I should explain more. We're using the Spike relays to build logic gates, connecting the outputs of some relays to the control inputs of others (fortunately, they work at 12 V as well as 5 V). In the end, it will be a four-bit adding machine constructed of 24 Spike relays (learning about how digital circuits work ), the result of which will be displayed using the fluorescent green camera lights from 2007.

We also need something to act as a user input to the circuit. The user needs to be able to switch this input between 12 V (a logical 1) and 0 V (a logical 0). Since we've managed to use only KoP components up to this point, I'm wondering if we can find another KoP component to do this job, just for the fun of making a complete computational circuit out of nothing but KoP components. The cRIO, sidecar, and power distribution system aren't involved at all here.

Thanks for the help.
