Works well
Does what it was designed to do and it does it well. I used it to replace a 'permanent' battery in a circuit board. It is now trivial to replace the battery. In additional, it provides an easy way to turn it on and off to factory reset the board. The switch is firm and not easily bumped on. The wires are 5 3/4" long , The case is 1" x 1.25" and 0.25" thick. Using a fingernail to move the two tabs will open the case.

Perfect little 2032 battery holders!
I needed to replace the CMOS battery for a small form mini ITX computer. Upon looking at the outrageous price for a simple OEM 2032 battery I decided to investigate whether I could use something like this battery holder instead of the OEM 2032 battery for this computer. So I bought some 2032 batteries here on Amazon and these 2032 battery holders and it worked great!The battery holders themselves are noting engineering spectacular but it does the job. You have your plastic housing and inside there are two copper(?) tabs that make perfect contact with the 2032 battery. The battery fit snug inside the holder, and the ON/OFF switch works well too. I'd say the amount of pressure needed to move the ON/OFF switch was about half a ~pound (~8 dry Oz) (~227 grams) of pressure. (Note: not foot pounds. Just pounds of force) I don't have the right tool to measure the exact pressure needed to slide the switch. But it took a little firmness to move the switch which is good so that it doesn't accidentally move ON or OFF. In other words, it's not a simple flimsy easy sliding switch that can accidentally turn ON or OFF.Hobbyist measurements:Width left to right: ~23 mm (~29/32") Just one 32nd over 7/8".Length: Straight down the middle top to bottom: ~31 mm (~1, 7/32")Depth: From the center: ~6 mm (~1/4")Length of wire leads: ~147 mm (~5.79") (~5, 4/5")There is an ON/OFF marking.

20% don't work
Very handy switch, nice size. About 20% of them did not work, so over-buy the quantity you need. The wires are less than 5" long, the description is confusing about that.

They were just as described
Looks like they will work just fine for my application.
