Defond White

I'm not an expert on mouse switches, but I keep buying them because I've got these cool holders for them and also I know sometimes it's hard to try out or get some replacement mouse switches, especially in stock in the US vs Aliexpress. 

Since this one is the basic one in their lineup it doesn't get a name, but it has a rating of 65g of force and is good for 50 million presses.
