Hi,

does anybody know which company (or companies) produces the shutter
release switches, used in all kind (film and digital) of photo camera?

I mean those switch which can have a "half-press" position and a
"full-press" position.
I guess they're kinda SPDT switches, but i don't have any idea
concerning where to look at.

Hope you know what I mean.

Thanks in advance.

It's probably fully custom, using a squishy rubber dome switch for the
half-press and a tact switch for the full-press.

Thanks for your answer. :)
Maybe you are right, but I find it pretty hard to believe. I mean,
every camera has it (and this means compact digital, digital reflex, AF
film reflex, from every make); IMHO it makes pretty little sense that
such a huge number of switches, like the one i refer to, are made fully
custom. It would be costly. And I guess the real costly part would be
the control circuits, the shutter, the sensor (if digital), the lenses
(if not sold separately), and the number of functions and programs the
firmware has. Not a switch.

Repeat: you are probably right, but to me it's kinda hard to believe
that switch is not a stock component and sold as retail or replacemente
part.

Thanks again :)

Right-o. I *seriously* doubt that standard buttons do not exist. The
most likely logical manufacturer to my thinking would be Alps
(pronounced Al-upps if you're speaking Japanese). Check it out. Mouser
in the US carries a (very) small portion of their line.

P.S.

Okay, here's a starter one from a quick search:

Use the key words etc. to find more.

Except for the fact that practically every camera has a unique case design,
and switch mount. As well manufacturers don't exactly all get together to
use the same parts, or even the same part design. I don't think that there
are any "stock" parts on any camera. I have 2 Minolta digital
cameras....pretty much the same design year...with ABSOLUTELY different
switches, due to the 2 of them having radically different case designs.
Hell...ALL parts, for all consumer electronic items would be dirt cheap, if
all manufacturers would get together, and standardize parts....but it just
'aint gonna happen.

Great! This is what I'm lookin' for. :-)))

I'm not sure to know exactly the name (or category) of this kind of
switch: what does TACT exactly mean? It is the first time I hear that
acronym (if it *is* an acronym).

It's not an acronym. It's short for "Tactile". Most such switches are
momentary single-acting.

Undoubtfully you can't be wrong. Mine was only a thought, based on what
i could argue "from the outside" (I never opened a still camera, and i
don't think i'll ever do, especially with mine : I just only would try
to build a battery pack-grip-portrait shutter release button for my
SLR)
Following your statement, I'd like to do some comparison: it is a fact
that there are hundreds (if not thousands) of models of op-amps, or
LEDs: they all do the same thing (amplify a small signal, or produce
light) but every single model does it in a particular way; i.e.: some
op amps have low-cost, some have small outline, some have hi-current
output, some need dual supply, some need single etc. Some LEDs are
white, some are blue, some are lo-profile, some are ultra bright, some
need low current etc.) Then, why not switches?
So, my humble opinion is that there are a certain number of tact-switch
models, everyone with its particular characteristics, and more than one
producer, so that your statement (lots of switch models) will be
verified, and mine (stock parts for retail sale or replacement) too.

Hope I wasn't such boring :)

Regards

With switches, things are greatly varied, due to numerous mechanical
considerations, as well as some electrical ones.
