Looking for a SMALL 2 or 3 amp switch

[proax9]

I am currently testing THIS switch on a mod that is running at 4.1 volts with 2.0 Ohm cartos.

It has been working for about 3 months now- but it is getting a little finicky. It could be because it's only rated at 12v 50mA.

Does anyone know of a 2 to 3 amp switch that is about the same size?

Thanks for looking

Your not going to find a switch rated much higher at that size. Really that type of switch should be used on a regulator with a control pin or with a mosfet to be able to handle the amps required to vape. There is quite a bit of mosfet info here in the forums if you dig around a bit. they come in some really small packages/ sizes. So if space is at a minimum you might be able to squeeze one in your mod.

I am not an electronic wizard-
some switches are rated in Ohms, while others are rated in "VA' (like 3VA @ 24VDC).
What is the relationship between a 3 AMP switch and a 3VA switch?

some switches are rated in Ohms,

I imagine that's just a typo. Most switches are rated just by amps and either AC or DC. You'll never get a tiny switch, with it's tiny contacts, to handle multiple/high amps. You need some meat to handle the load and the arcing (more troublesome with DC). And a cheap high amp switch isn't always the answer as the service life is probably short.

Most folks press their switches far more than they realize.

Say you vape for 4 actual/total hours a day, that's 240 minutes. If you only press your button two times a minute, in 3 months time that comes out to 57,600 presses. I'm sure many folks will double that amount.

If you 'search' you'll find hundreds of posts regarding your questions.

The VA stands for Volt-Amps. Which can be confusing. Here is a data sheet pic of 3VA 28 volts dc converted to regular amps. So @ 28volts DC it can handle 10mA. Tactile switches are made for logic level signals pretty sure your not going to find one that can handle power. Still Going to recommend adding a Mosfet to one to handle the amps.

Thanks, I appreciate the info.
