Yeah I noticed it was a MOSFET after I typed it. Maybe you need to describe what this thing is supposed to do. I gather you want several students to be able to activate a device by them each having their own touch switch? I would use a JFET instead of a MOSFET. I thought the clock might be some sort of sequencing circuit because as you said Roff, the MOSFET circuit would deliver a pulse which is all that is needed. That pulse could be used to toggle say a J-K flip flop off and on.
