Sure, it can switch 20 times a second, but only if you have NOTHING CONNECTED AND NO POWER.

At best you can turn it on and off 6 times per minute if you plan on attaching a motor to it. The spikes really just can't do speed controlling.

Yeah, you are really much better off just using a Victor - they're not all that bigger than the spikes, you can probably squeeze them in somewhere.

I have to disagree. 6 times per minute? 10 seconds between switches? That is patently untrue. I can walk over to the robot and toggle a switch a few times if you'd like proof.

Spike relays are meant to give a on signal, reverse signal, and a neutral signal. As someone said earlier, you should use a speed controler if variation is what you want.

I had this idea, but my team shot it down, I later learned that a relay is for full forward or full back or not at all, and speed controlers are used for motors. I hoped this helped.

yeah, i see why you might want to use a spike. But frankly, unless you've used every PWM port, your team will basically need to deal. I'm not trying to be rude, but why even risk (i'm not sure of the electrical component, so i wont take a side) unnecessary damage to a SPIKE when a VICTOR is designed for exactly this purpose? They're not that much larger, and it sounds like this is exactly what you want.
