QTEATAK 20 Pcs 6mm 2 Pin Momentary Tactile Tact Push Button Switch Through Hole Breadboard Friendly for Panel PCB

When I breadboard a tactile switch in an electronic design project, I hope for good contact, and durability in the switch. In the manufacturer’s design, the leads are long enough to make good contact when used with a standard solderless breadboard. These switches were used successfully to push-on then release-off the contacts. In our build, pushing on and then releasing the button allowed our supporting circuitry to trigger a short bounceless pulse to the IC’s clock input. This was used in a simple digital design that allowed 4 leds to binary count from 0 to 15. The switches were reliable and fun to use.

This was a perfect replacement for the pushbutton switches in my DigiTech RP300 musical effects pedal board. It was a very easy matter to unsolder and remove the old switch, which had quit working, and solder in the new one. The dimensions are all exactly right.

We have a $170 Zojirushi water boiler that works perfectly, except that over time the switch for the "Unlock" button stopped working, so the water boiler no longer dispenses hot water. A replacement water boiler cost $170 (+ tax).Not ready to throw away the old one, I figured there is not much to lose to try to repair it (otherwise it goes in the trash). Only needed one switch (20 pcs were in the pack, so 19 more spares). I took the entire water boiler apart (disassembly is from the bottom, with a security type star bit), removed the old switch, and soldered in place this new switch. The water boiler is now working again perfectly. The only difference is that the old switches used in the water boiler were silent, and this switch has a fairly loud click. Not a big deal, but the difference is noticeable.For take the price of the 20 pack, divide by 20, add some labor, and the cost to fix the boiler is well worth it. Just check the pin spacing and height for whatever you are trying to build and repair to make sure it fits your need. In my case, both height and pin spacing (pre-measured with callipers against website information) ensured that the part was a perfect fit.

I had to build lighted wands for a HS production of Harry Potter. I used these switches for lighting an LED in the end of the wand when casting spells. They worked wonderfully.

I would buy again if the need comes again.

Great Parts

At 6mm by 6mm this is a very small switch. With that size you can put a switch every 7.5mm on your breadboard. The tactile feel is very good. A firm but not hard push is required. You will feel a positive drop in the button when contact is made. About 2mm of the wire pins extend into the breadboard making positive connection. The pins are not round, so the edges will generate sufficient force to make contact. I am very satisfied with my purchase.

Identical to the failed switch I removed from an instapot milk frother. Now I'm ready for 19 more repairs.
