I am trying to find a device that will function essentially as a four pole switch that will toggle itself 8000 time a second, with throughput of about 5 amps and voltage of about 40 volts. Also if the frequency of the device can be changed, possibly by hooking it up to different oscillators, that would be a bonus. What is this device called and where could I get one or build one? Thank you.
Answer 1:

I suggest you to go to an electronics hardware shop and ask someone that works there for a power switch with the characteristics that you are mentioning here.

The best thing you can do is try to purchase this device instead of making it, unless you know about electronics, and you are very familiar working with it.
