can anyone identify this remote control switch?

[[email protected]]

One of the buttons in my car remote door opener got stuck in the
pressed state. This causes the alarm to turn on and go off while
driving.

Here is the guilty switch (two jpegs 600x400):

The respective button is indeed broken (won't click when I press it).
Where can I get a switch like this? Looks very easy to replace. There
is no part number printed on it. Thanks a lot in advance!

Dealership ... you know, the guys who sell the cars and the service and
the parts.

Hi!

It's just a simple microswitch...lots of companies make them and you could
probably pull something suitable out of a dead piece of equipment.

You could probably also just remove the switch, which would be the fastest
thing to do if you don't need the alarm function.

I doubt they will have the individual switches.
Sorry, I am new to this group, but... if everyone here went to a
dealership for a little problem like this, wouldn't it contradict the
essence of the group itself? I like fixing things myself, especially
when the fix is obvious.

Thanks! I am also thinking of transplanting one of the 3 remaining
good switches into position 1. I only use buttons 1 and 2 (open/
close). I never use buttons 3 and 4.

That would certainly work as well. If you do elect to replace the failed
switch, replacements could be had from dead CD players, some types of garage
door opener, possibly other keyless entry remotes...pretty much anything
where a button gets pressed that only results in momentary contact taking
place might have the kind of switch you need.

I'm really quite surprised to see microswitches in a keyless entry remote.
The most common approach seems to be the same that is used with most remote
controls...a rubber dome that when pressed puts a conductive "dot" against a
pad on the circuit board and completes the circuit.

This one has a rubber dome that presses the button on the microswitch.
The advantage I guess is that one feels a distnict "click" when one
presses it. The disandvantage is obvious, too. The thing failed after
~4 years of use. Failed when I gave my car to a friend: he probably
was pressing the button too hard.

not unlikely that the switch failed, but are you sure the solder isn't
cracked?

It's definitely the switch (it does not "click" while the other 3 do).

Search for "miniature tact switch" or "tactile switch".

Here is something that looks similar:

I meant to replace the unit; not buy individual parts ... I thought that
would be obvious!

The vast majority of humans cannot successfully desolder and resolder at
this level.

Good luck.

Then you want to post on

More evidence that you're on the wrong newsgroup.

I find those sorts of responses annoying, too. They make you feel that
you need to apologise for asking the question.

Anyway, I recently did a job like this for a mechanic. I charged $30
for parts and labour, but the switch that I used was not dimensionally
identical to the original. Worse still, its tactile response was
noticeably different to the rest.

BTW, I've done several such jobs. In each case the PR value was worth
more than the pittance that I received.

I transplanted a good switch from a button I don't use anyway into the
place of the broken one and it works like a charm. Took me 10 min to
fix. Very rewarding feeling, plus, got some praise from my wife .
Much more rewarding than going to a dealership and getting a new unit
(and I am sure took less time).
