Hi I would like some advice on what you think I should use as a passive switch for my NPN or MOSFET transistor. I am trying to PWM pulse with modulate an electromagnet with a 12V 3.6A battery and I want to have a passive switch. I have tried to use photo interrupters in the past but I am not smart enough to know how to make all the connections. If you have any ideas I would very much like to know, Thanks.
