tactile switch leads?

[icecycle66]

I hate asking questions like this, I feel like i'm bothering people.
Whatever.

Why do tactile switches in Digitech and Behringer pedals have 4 legs?

All the other switches I find, and want for rehousing purposes, have two legs.

How am i supposed to cram 2 legs into 4 holes and have everything work the same?
