Grizzle;
I for one would LOVE to provide you with helpful advice.... and trust me more than one would also help.
However, your requirements are a little vague and confusing.
I'm enclosing a small schematic showing what I am guesssing you require. One is for a ground referred load (N-chann fet), the other for a battery referred load (P-chan fet).
Of course, the actual fet part number will depend on the the actual maximum voltage and current required
Thank you very much! The only consideration as to current and voltage is the isolation between the normally-open and normally-closed contacts, as if isolation between them breaks down, one would have a dead short between the poles of a battery or battery pack. There simply is no current flow or complete circuit. What I am looking to do is to connect one pole of a battery or battery pack to an output, only one at a time, and then the other, and to alternate between the two with some kind of variable oscillator, such as an led flasher circuit or alternating led flasher circuit to control the rate.
As it is, what I am using is a AA battery-powered clock motor and an analog SPDT switch with a long lever (the clock hands have been replaced by a thin aluminum disc cam with cutouts) to achieve the same effects. However, the manufacture of these is a time-consuming process which requires skills, both of which conditions will impede the spread of the idea. I want to make something that the 10-year-old electronics hobbyist can throw together on a circuit boad in a few hours.
Again, thanks for your time.
