I need to replace a standard two position (3 leg) switch with SCR's. The reason is that the standard switch is not fast enough when switching over the two circuits connected to it. Can this be done? And if so how?

I also have MOSFETs available if that would be a better idea? Searching around I read somthing about using two parallel SCR's to make a Solid State Relay...could this be the answer to my problem...and how would I configure the SCRs for this?
ok, well what are your part numbers on the mosfets? what is your power source, and what is your load? how do you plan to trigger your switch on and off?
mosfets will conduct in both directions, btw..they're not like bipolars, once you turn them on the current can flow either way... the p or n channel just tells you which way you have to pull the gate voltage from the source to turn them on...
i have N channel mosfets...+ allows s-d and - closes s-d...I thought this would be alot easier than it is. I have a mechanical two position switch currently on the circuit and just need to make it solid state so that it switches faster than I can manually switch it...
