DaierTek 6pcs 12mm Momentary Push Button Switch 12V Waterproof Power Pushbutton Small Round Chrome Stainless Metal 2pin N/O

High quality switches for the price, super easy to use and fit perfect

One failed prematurely, the others work great, installation was easy.

These make excellent kill switches for electric guitar. You simply drill a 1/2 inch hole to mount the switch (put painters tape on the area where you’re going to drill to minimize chipping the finish) be careful not to hit any wires or components inside when you drill. Solder two wires to the terminals on the switch then solder them to the positive and ground terminals of your output jack. This will create a short to ground when you push the button of the switch. This setup is best because if the switch eventually gets dirty or wears out, you will still be able to play your guitar. See my video for a sound example.

These look great and feel great and work perfectly. Just don't lose the jamb nut that comes with it. The body threading is indeed M12, but the pitch is only 0.75 mm (at least on the ones I received), which is much finer than most M12 hardware you might find.

After just a few uses the button failed and stayed stuck in down position.
