The XA release is an electrical switch with a rubber pad between two metal
plates. As the pad is compressed, it conducts and completes the circuit
between the metal plates. The switch itself moves only a fraction of a
millimeter (or whatever).

| As you know from using an XA that is in good shape, the shutter button was
a
| completely new idea and design. Maitani wanted the softest of release
| pressures because beginning shooters pressed the shutter releases too
hard,
| creating camera shake. Olympus called this shutter release a 'pressure
| sensitive conductor element" which leads me to guess that unless you can
find
| say- a broken wire- the assembly is not going to be user fixable. Kinda
| sounds like the whole thing is modular in design, one may have to replace
the
| entire assembly. Side note- Maitani considered heat-sensitive and
| electro-chemical buttons that would react with the photog's body heat and
| electrical current in the skin. These ideas were not followed-on because
what
| would you do if you were wearing gloves on a cold day?! (So, not all
| Maitani's ides were golden).
| I think John H. will have your answer.
