amp rating on a switch

[Tarnacc]

I have been reading through some of the older threads but I am still a little confused about the amp rating on switches. Lets keep it simple and say I am making a basic single cell 3.7 mod with a 14500. Can I use a tiny tact switch for this?

I see the amp rating on these switches is usually .5 amps. What is the trade off? If I use this switch in the above example does the low amp rating lower the efectiveness of the atomizer or will it still provide the same performance of say a 5amp switch but wear out faster?

In a straight battery configuration like you describe you need a higher rated switch. In my experience, an under-rated switch will BOTH wear out faster, and cause a higher voltage dropout than a better rated switch.

So higher voltage dropout translates to less yummy goodness?

Thank you for your patience and responses. In a simple single cell setup, what is the lower limit in a switch? Is 3amp enough? Can you tell a difference between 3amp to 5amp?

3A switch will be fine, anything more will not affect your vape either way.

Ohm's Law: Current = Volts / Resistance. Volts will be your battery and Resistance will be your atty/carto. So as long as your switch is rated over what your Current calculates out to; you should be good to go.

3amp is plenty. It will only pass as many amps as the system draws, and at 3.7v, even LR atties only draw about 2.5 amps.
