YXQ 1x5 5 Keys Matrix Membrane Switch Keyboard Keypad MCU Control Panel Button(3PCS White)

I used this to replace a 5 button key membrane and it works perfectly. Tested after install and just kept a note with how the buttons correspond with my machine. Manufacture wanted 200+ for their custom keyboard membrane . These worked fine at under 10 for a 3 pack

Keypad worked as described. It does not come with a connector pinout but it was easy to determine with my ohm meter.

Wish there was a 'blanket version offered.Bought 2 packs as needed to try and disassemble to make custom top layer.Added own top layer, and discovered other portions of button tops increased in height when 1 was pressed. So, there appears to be some sort of (not viewable) communication between button cells. This is good thing. Buttons are not fully sealed because of this and area around cable connection does not appear to seal well.That being said, I may have disturbed seal while removing top layer, so not pronouncing as bad product.Connector quality is iffy, already found 1 that has Intermittent contact to middle SEL button. Looks like fingers slightly misshapen. Recoverable, but shouldn't have to.

Would be nice if there was a Pinout on at least the listing I'll have to go get my multimeter out not the end of the world but a little frustrating when I'm in the middle of a coding storm.Works awesome as a direct connect for Arduino though, just with there was pin designations anywhere.Reducing this from 3 to 2 stars for doing your job for you here's the Pinout:From bottom up facing you the ribbon pins are as follows:Bottom: voltage in2nd from bottom: Select3rd from bottom: Dec button4th from bottom: Inc button5th from bottom: Before button6th from bottom(top of ribbon): Next button

I got three of these in a package. On 2 of them only sw1 & sw2 worked. On the third one all 4 of the switches worked originally but sw4 quit working after about half a dozen presses. so, I cannot use any of them.

I tried these out as shutdown buttons on raspberry pi’s, they work fine but the pigtail is utterly unnecessary. If one is needed it can be added but if you don’t want it you can’t really get rid of it.
