Toggle Switches

[Jon Stratis]

The best advice you can get: stop by your local Radio Shack and check out their drawers of component parts. Most of the switches, buttons, knobs, and such that are available there are suitable for use on the robot or on your OI. You get a wide selection, and can actually hold them in your hand and try them out before buying.

Depending on how many modes you have you can even just use a little jumper on the Digital Sidecar's digital I/O lines. You just need to connect the ground and signal lines together. More of a pain to set but less effort to build and it doesn't weigh anything.

Of course teams with lots of complex options would want something else I suspect.
