That's exactly what's found in Atari joysticks.

These switches need some sort of flexible sheet or button above them. 
Atari joysticks use the latter approach.  When pressed, they collapse with 
a tactile snap and bridge contacts on the PCB.  Release pressure and they 
snap back to the original shape.  I don't think they're a good choice for 
a homebrewed front panel.
