Normally these buttons get damaged from pushing them too hard. The tactile switch stops bending and making contact, or it just bends all the way and wont stop changing your settings.

  1. Turn off the transmitter and take out the batteries.

  2. This is the button that's not working. All the other buttons have the same parts so if a different button is damaged, you can replace it the same way.

    • On the lower side of the transmitter there is a small stick holding the compartment cover.

    • Push it with your Torx Screwdriver so that the stick slides out, releasing the compartment cover.

    • With a spudger o a small flat head screwdriver, carefully remove tactile switch.

    • It's not too hard to loosen up but you should do it softly.

    • Notice the metal contacts and the direction of the tactile switchs. The small metal tab faces your right.

    • Place the new tactile switch. I didn't use glue but a tiny piece of 2mm adhesive sticker tape can work just as well.

Hi -

I just want to say thank you! I made the repair exactly as shown and put a teeny drop of rubber cement in the middle of the new tactile plate to hold it in place, happy to say it all appears to work fine. As for the part itself, the part # is the same for the G3 and you can order from them in CT, USA.

Cool! I'm glad the guide helped you with your repair! do you happen to have the website for the store that sells them?



Angela Penaherrera -

Yup! This works. :-)

I have the Sennheiser ew100 G3. The "down" arrow button was stuck and I couldn't change anything in my menus. What a pain!

So, I ordered two of the buttons from this last week (item number 072512). At fullcompass, they call it a "Switch, Power SK100G2/SK100G3". It's the same button for the up arrow, down arrow, on/off and set buttons. It was $1.99 each and I ordered 2 plus $3 shipping.

I used a small screwdriver to gently pop the old button off and it actually came out in two pieces instead of one.

Anyway, I placed the new button on the little prongs and made sure it faced the same direction as the other buttons on the board. I put a little (and I mean little) piece of electrical tape over the side of the button. I'm talking like 1mm wide by 1cm long.

Screwed everything back together and voila! Working Sennheiser. Saved me almost $100 in repair. :-)

Always happy to know of a successful repair! Good job and thanks for sharing your story ^_^

What holds the new switch on? How are the contacts made without soldering?

Charles Kaiser - Reply

Yes I'm curious about this too. The buttons are soldered to the board from what I can tell.

I put a small piece of 2mm double sided tape on one corner. The soldering that was there was minimal, just to keep it in place from the looks of it. It has not given me any problems and have now been using it for more than a year!

I must be doing something wrong. The button seems to be soldered in place. I've tried gently prying it but it does not pop off, move or anything. Any suggestions?

Success! The first time took me about 25 minutes, but the 2nd time took under 15 minutes. Would be good to have a few pics explaining the reassembly & other loose pieces that can fall out along the way. I would keep a 2nd assembled unit at hand to look at to help you orient the pieces when you reassemble.


Regarding prying off, just take a flat precision screwdriver and carefully peel it off. Rotate around to each side, each corner until you can get a bite, and then start pulling it up. Mine ripped into several pieces but it's going in the trash anyway. Get the area clean enough so that the 4 little metal corners have no debris left around them.

Regarding attaching, I used toupee tape (double-sided, good stick) and cut a narrow 2mm strip on one end, then I cut several little triangles to have on hand. I attached a little tape triangle to the underside of the new switch, peeled off the tape backing, and carefully placed it on the circuit board using a tweezers. Then pressed down semi-firmly on the switch with a blunt end to ensure it's secure and won't come off. Put batteries in and tested good.


p.s. btw, my G2 buttons had all the small metal tabs on the Left side rather than the Right, so I'm not sure if it's critical which direction the tab faces as long as it's square on the posts.
