Does off mean off?

Generally on a batt disconnect switch esp. after market, off means off.

I however, bought a cheaper switch on Amazon a few years back that was basically a screw that tightened to connect the two plates to turn the battery 'on' and unscrewed to turn it off. If you turned it too far 'off' the plates would angle a bit and actually reconnect. I learned my lesson!

This is the type I purchased, after turning it to "off" position I checked inside batt. light panel, co detector ect... everything was off so it seems to be doing the job.

Thanks for the quick replies everyone, I think the original battery had such a short life due to draining down too many times. I will reconnect after a couple weeks to see where battery life stands and figure a pattern from there.
