How much current does a 6V ride on typically pull?

I'm looking to replace a switch in a 6V ride-on but need to know the operating current.

The best I estimate is a 6VDC battery (OEM) is rated for 9.5Ah and google tells me it would last 45-60 minutes, so IOW about 9.5-13A. That sounds crazy high to me.

Can you find a part number on the old switch to find it's data sheet?

Buy one that's rated for way more than what you might need and don't worry about it. :shrug:

Math says 13A? Get a 20A or 30A switch. Not going to hurt anything.

Just oversize it unless you want the switch to be a fuse.

Remember V=IR, P=IV
6 and 12V devices often use more current than you're conditioned to thinking about in the context of 120 or 240V.

As the saying goes, a watt is a watt is a watt. Power can be a good unit to think about in that context.

I generally agree however the switch then becomes MUCH larger for the extra current.

It would be helpful if you posted a picture of what you're doing and a link to the replacement switch you're thinking of using.

I think you're talking about a "ride on" toy, but I'm not absolutely certain that's the case.

Yes sorry - I am talking about this:

Power Wheels Thomas & Friends Thomas with Track [Amazon Exclusive] [amazon.com]

Actually a dual wheel drive 6V (which is uncommon) but it includes a ~ 6 ft dia. circular track (It can run on the ground too). I'm thinking about putting a switch beneath it where I can toggle it to remain on (run around the track) rather than having to depress the thumb button.

First, that probably isn't as safe as the thumb button. A few scenarios that come to mind: trying to jump aboard a running train, run over by a run away train, runaway train with a passenger, derailed train trying to run into a wall or something and getting hot (a fuse becomes more important). This sort of thinking is why the mfg doesn't give you the option oob.

Now that we've covered not maiming anyone or starting any fires, a "toggle" type switch would probably be easiest. A rocker would also work but mounting is a bit harder. You could also pair a keyswitch and a rocker switch or rig so the 'thumb button' would stop it if it was in constant on

What switches are you looking at specifically?
