Why are magnets better than springs?

[Miata GT]

In many mods the spring not only keeps the switch parts apart but also conducts electricity. In my mods I have always swapped out for magnets where possible.

As has been stated quality magnets with just the right repelling force make all the difference, IMO.

If the spring is part of a conductive path, wouldn't it typically be the case that removing the spring is basically removing a resistor from a pair of resistors wired in parallel?

Obviously if the spring had higher resistance than if there were no spring, removing it would be good. But if the spring has low enough resistance, its existence seems like it would improve the situation by lowering the overall switch resistance.

Am I thinking about this all wrong?

Well the spring does have a resistance, as does anything that allows electrical continuity through the circuit. And when the pin on the switch touches the negative contact of the battery, electricity flows through the switch (and the spring) because this is all in contact with the metal of the mod that allows the flow of electricity. On some poorly designed mods, the spring may have a higher resistance than what many sub-ohm vapers wire their coils... resulting in a hot button. But, even if the spring resistance is very low, the resistance is there and will cause a slight voltage drop.

A pair of magnets that don't ever actually touch does not have continuity through the magnets, so this setup will allow for less voltage drop in the mod (although the difference will be very small).

there was one dude here somewhere with a video that uses a tip condom cut to fit as a spring, i tried it with my T.O.L...... and it does work well with the post type switches.
just an alternative to consider....some swear by magnets but not me, i just prefer a good spring...it's just a choice...not bashing any switch that works for the user.

i read a lot about magnet and spring. i have spring in my penny and nemesis. they are both very smooth and works great. one the other hand, my 4nine which i started to carry today is very crunchy and not smooth at all. small sample data so i won't know what is the real situation. need more mode to study this in length.
