Sorry if this is a really basic / off topic question but I've used these toggle switches for all my battery powered projects so far to physically disconnect the battery when turning the device on (helps a lot with battery life):

I usually buy them in packs which include a mix of momentary switches, toggle switches, etc, so I haven't been able to find the name of them yet.
now I need to buy them in bulk for an upcoming project, so buying a pack of 100 switches to use is not an option! if you know the parameters for parametric search in mouser/digikey, please list them below. otherwise if you the name of them, that would help too! When I search for toggle switches I usually find things similar to a PC power button which is not what I want!
