Fire button heat

[preq2003]

Hi guys, as title says, my mod's fire button get heated up after several fire. This is my current setup;

device: MS mech mod
Battery: 16350 protected trustfire
tank: AGA T+ with silica wick at 1.0ohm

I've tried with 16350 unprotected IMR battery, resulting the same heat.

What might cause the heat actually and any solution? Any opinions, suggestions and advice is highly appreciared.

Thanks in advance...

Current = voltage/resistance. 3.7/1= 3.7 amps. That's what heated up your fire button. It's also 13.69 watts of power. Think 15 watt bulb close to your hand.

In a mechanical mod, the current is the same everywhere in the circuit and produces heat where resistance is encountered. The switch will drop voltage also and that produces heat from the resistance of the contacts. You are experiencing the switch contact load heat of firing that 1 ohm coil as well as the heat spread from the atomizer coil through the case.

In an electronic mod, a low current voltage switched by the fire button is fed to a MOSFET gate that switches the current on and off to the coil. The switch current is in the low milliamp range.

Thanks a bunch DaveP for your explaination. Thus does this mean it normal in mech mod? so increasing the ohm will reduce the current and lower the firing button heat right?

Yes increasing the ohms should cut back on the button heat. I suppose its fairly normal for a mechanical mod however I don't seem to really notice it and I run really low ohms
