These are all of the most common micro tactile momentary switches that I have come across, or used in my years crafting sabers and sourcing supplies. All of these switches are momentary and work well with soundboards from Plecter Labs, KR, and the Proffie Boards. Some have longer legs on them than others and can be trimmed down as needed. Often they have 4 legs, remember that only two are needed for most setups and trim the other two off with a pair of flush cutters. Here are a few of the dimensions for the most commonly purchased switches. More to come.
Switch #19 - 6mm L x 3.5mm W x 2.5mm T
Switch #21 - 7mm L x 3.5mm W x 3.5mm T
Switch #12 - 7.3mm L x 3.5mm W x 4.5mm T
Switch #14 - 6mm L x 3.5mm W x 2.5mm T
Switch #17 - 6mm L x 3.5mm W x 4mm T
Switch #18 - 6mm L x 3.5mm W x 4.7mm T
