    Toggle switch with MOSFETs

    Is it 4 options like source1, source2, both, and none? Or just two: source1, or source2 ? It would be convenient to simplify with two mosfets. Battery energy does not need to be lost. Performs an action of running the load.

    Solenoid Help

    I would go with Minder suggestion. More turns of smaller diameter wire. Visually, it seems the solenoid is not original, or was hand-wound; perhaps with the wrong coil in a previous attempt to fix something. I think I have seen similar buzzer coils used in clothesdryer machines... -->...

    Resistor wattage confusion

    Welcome. Seems your supply is still in some zombie state. Use a voltmeter to probe the output, and the voltage across the resistors. Can the voltage be adjusted or is fixed at some value ?

    What's 'fast enough'?

    Internet providers are there to profit, not to give you a service. If you are not satisfied on performance, upgrade only in small steps to achieve your needs. Better eliminating bottlenecks first, like the WiFi that nobody can live without now. (There we go to please the comfort !) I do...

    limiting a heating element in a water heater?

    A way to limit the heating current is to connect an incandescent 230V light bulb in series. The higher the wattage of the light bulb, the more heating your element will provide. If the wattage of the heating element is around 500 watts or less; a dimmer rated for that is your most convenient...
