Bad MCC push button connection | Replacement Part

Post by yanga001 »

Hi everyone,

well i am getting tired of holding down the button to get my AC to stay on, i took apart a backup one i had and managed to break the push button switch. Took some measurements and found this seems to be the same switch available on digikey.

https://www.digikey.ca/en/products/deta ... FP/2296958

17.5mm height, 6mm wide pins, 5mm spacing between pins.

This seems to match up with what i got from the broken board.

I'll try to desolder on the dummy board first before going to the current good one.

Hoping this will keep it fixed. Anyways if you are looking for a part that will fit then i believe the one above is good,

I've not yet had mine apart, but I'd love to see pictures of the board. I've got an indicator light that's not working. Do you have any fancy soldering equipment?
