Switch Amp Limit

[jackcustard]

Just seen this mentioned for the first time.

Can someone explain it to me?

Some switches don't have a high amp rating, so if they are used in an unregulated mod that pulls more current on 'fire' than the switch can safely handle it will fail. The contacts will burn out.
This is why Mosfets are used in mods because they act as semiconductor switches, they handle the high current allowing virtually any low current switch to be used.

its simple ,switches are built to be able to be used upto a certain power (amps)
if you try to put more power throw the switch than it can take bad things happen(ie it can melt and short/weld its self on)
on a regulated mod there is trickery in the board so this is not a prob(full power dont go throw the switch just a signal for the board to do its thing)
on mech box,s the the peps in the know tend to put in a mosfet(relay) to stop switch meltage

hope that helps

ninja'd lol

Okidoki...

So what is the amp limit of the switch on my gizmo?

How do you find out the switch amp limit?

[Bobsbeer]

That will be difficult unless you can get it out and look at it.

the amp limit on you gizmo is a bit different as the switch is in swich terms a beast
why for you asking has it stuck down at some point

[jackcustard]

It stuck down last night but that was when i was getting shorts and the problem was found to be in the base of the spheroid. 510 plate touching both pos and neg posts. Fixed now.

Also got button stuck down with the emow but once again due to shorts with the coil getting crushed.

Spheroid much better after putting spare posts on the pos post was much higher than the neg where it touches the 510 pin.



When it did happen i just turned the atty breaking the connection. Probably lasted for under a second.

Tested battery voltage after and they seem to be fine...

It can be taken apart fully bob. What do i need to do?

Does the fact the switch uses magnets effect the amp limit?

Can the magnets repelling power decrease? If so how?

[decoy]

rc spring stops that happening lol
dont worry about it ,it only happened because you had a dead short and the little screw welded its self to the magnet on the batt(sorta like a spot welder)
mind you can see that being fun with the low pro switch to get your fingers in to free it off in a rush

just to clarify jackcustard the switches that have amp rating as such are the tactile and push button types as well as rocker switches
tactile switches are what is on the vamo ,zemax,vtr,mpv ect
push button switches are what you will find on square home made type boxes

now the problem with that is if you sub ohm on the box and the swich isnt man nuff it melts hence the mosfet i mentioned

on the gizmo amp rating is not a prob if your atty has a dead short in it and it not the coil bad things happen that why i always chuck a fresh build on the vamo and to check it will run np at 4.4 volt
