Your post could use a little more info:
- do you want a latching switch that stays down when clicked?
- does it need momentary functionality?
- will it need to handle the entire current load from the battery stack or is it just going to toggle a MOSFET (or other high amperage circuit)?
- if it's toggling a FET circuit does
that circuit need to latch so that the light stays on?
I found this document quite useful for understanding the terminology that the switch industry uses when marketing their products:

My biggest problems when searching for switches a couple months ago were:
- switches that can handle DC 1A+ are
big: most hovered around 14-20mm tall and 12mm cross-section
- momentary push-button switches that can handle < 50ma are
tiny but you need to build an e-switch circuit (like Steve Ku made) to handle high current flow and perform software latching
- none of the datasheets will tell you if a latching switch is
also momentary, and the customer service reps I spoke to often didn't understand what I was asking
Judco, ALPS, NKK, e-switch and Apem are a few manufacturers I noted as having small-ish switches that can handle higher current.
After all my research and buying a large selection of samples from those companies, McGizmo's switch really does offer the best compromise of performance/quality/function vs. size. The McClicky isn't small but if your design can handle it, they are probably the best bet.
