Hey everyone!

A few months back I bought a Xbox 360 wireless controller at a garage sale for cheap (it was pretty beat up though).

I've removed the connect / sync button tact switch from the board (kinda stupid thinking back on it) but since it's off I'd like to test it before trying to resolder it to the board.

How would I test this switch?  I'm seeing 3 prongs coming off the underside of the unit ; can I use a volt meter to make sure the button is working?

Thanks! :D

its a tact switch. yes, test it with a meter for continuity when pressed.

Thanks for the reply Modded Matt :)

I Googled around but didn't find any info on testing tact switches.

I'm pretty good with a volt meter, but how do I do it?  I'm guessing something like put the positive lead of the volt meter on the leftmost prong, put the negative on the rightmost one, then do something with the middle one?

No.


Set your meter to "Ohm's" or resistance.

Hook any which of your test leads to the middle pin first and the other test lead to any one of the outer pins.

press the button.

Look at multimeter for a change in resistance.

If the meter says anything under 1 ohm then the switch contacts are "closed"
If the meter says "OL" or infinite then the switch contacts are "open".

Unpress the button

Look at the meter again...

Are there any changes on the meter's scale?

If the meter's scale changed then the button is good.

If not test the other pin on the tact switch and repeat the steps above.


If there is no change at all after testing both sets of pins on the tact button then it's probably a bad switch.

Thanks!  I haven't had a chance to test this yet, but once I do I will post here with my results :)

Hey everyone,

Well, it has been like 6 months but I finally tested my sync button :P

Long story short... the tact switch for the sync button works! :D  Unfortunately while trying to solder wires to it I broke 2 of the 3 pins off, making it useless.  Luckily I had a spare semi-broken Xbox 360 Guitar Hero controller that I grabbed the sync button tact switch from :P

This sync button only has 2 leads on it.  1 goes to a ground, the other is the signal to the motherboard; does it matter which pin goes to which?  I'm guessing not, because they just connect and ground out anyway.

Anyway, I just wanted to give an update and share some info that might help others :)

Your guess is right! It doesn't matter which pin of the switch goes to ground and signal.

I am glad to hear that everything works again! (:

Thanks FOOKz™!

Yeah, I'm happy it's in the home stretch too :)

I have 1 small mod in mind to replace my Play & Charge Kit; I'll probably make a new thread on that :)
