Switch for vaporizer

Guest
I use this switch for a hot vaporizer.

I noticed the switch get pretty warm when vaporizer is running.

It draws 5 amps, but the switch is rate at 3 amps.

Does it look like any problems based on the picture?

That is a dumb ass question. If something draws 5 amps,use a switch
rated for 5 amps or more.

It may go forever and not cause any problems, or it may overhear and
cause a fire in the next day or so.

I would toss it and fit a decent 2 pole 10amp switch, why take chances ?

Yes. Heating goes as current squared, and the contacts will probably
wear with use and make the heating worse. It's a fire hazard.

Scientists should know that.

Why the hell would you use a 3 amp switch on a 5 amp circuit?

Yup, That sucker looks as if it uses insulation piercing connections,
which makes for a quick assembly, but poor connection. A better
quality switch would be a good idea.

There is nothing wrong with that switch if used properly.

I have used them for many,many years with no problems.

Many lamps sold have them.

Yup, most days it will work. It wouldn't get UL (etc) approval if it
didn't. Cheap, dirty, maximize profit, is the ultimate manufacturing
goal. It a few fires or lives are lost, that's not the concern of
the profit makers. We are expendable after a certain profit/cost
point is reached.

I know. I designed this stuff. In the last analysis the
bean-counters have the absolute say.

But now that that's out of the way... if it is getting hot/warm and
not producing action, that thing is either inefficient or you just
have a poor connection.

The standard for what I will accept, and what the bean counters find
satisfactory, are different.

It's your life and your choice.
