Let me be more precise,assume I have two batteries if I use just a single switch for each battery then I can only have batteries in "one " polarity, because if I oppose the polarity then my single mosfet conducts through the body diode.There are probably many possibilities, but we need to know the whole story.
We would appreciate more precise information.Let me be more precise
Sorry, but your schematic doesn't make sense for the two coils that are connected together.I have two batteries if I use just a single switch for each battery
It is not a specific design, more of an idea in general for me to understand whether it can even work before I build it on a tabletop, therefore I do not have specs.We would appreciate more precise information.
Like what voltage, what current, what other requirements (power, efficiency, ON-resistance, timing...) in values and units .. are you talking about?
We don´t necessarily need to understand the purpose (I can´t imagine what it is good for), but if we knew, we maybe could support you even better.

then simply use an analog switch IC.It is not a specific design, more of an idea in general for me to understand whether it can even work before I build it on a tabletop, therefore I do not have specs.
basically I need a bidirectional switch,I‘ll just add my voice to the others who are trying get you to present a schematic or a description that makes some kind of sense. Your latest “schematic” does, what? Maybe the H-bridge Dana showed is what you want, but it’s really hard to tell what you want.
I am starting to think that a common source series N fet arrangement could work for me, in either current direction the potential difference is then only across one of the two FET's , so in theory a simple drive circuit capable of giving 15 volts above the common source should be able to turn the FET's on when needed if both gates are tied together.Use a Triac. Bi-Directional Switch
A triac is not a bi-directional switch in the sense the OP wants. It has to be triggered.Use a Triac. Bi-Directional Switch
Has a switch to be triggered ??A triac is not a bi-directional switch in the sense the OP wants. It has to be triggered.
i don’t know what that means, but I still wouldn’t use a triac here. You need to maintain a minimum current or the triac will turn off. But, considering the lack of useful information from the OP, maybe a triac is suitable.Has a switch to be triggered ??
