implementing a DIY button array


for all the tact switches i’ve used, i’ve never come up with a good strategy for creating a button-over-tactswitch system.

how do you guys handle this?? i’ve taken to re-purposing keyboards to deal with this issue, but i’m facing a situation where i need a relatively small button array. i bought a second hand receipt calculator from a thrift store and took it apart and created a tact switch array underneath the keys, but it feels kind of flimsy and i’m not proud of it. it works, but this is for a musical apparatus and needs to be durable.

any suggestions would be wonderful. thank you for your time.


How many button / switches ? Maybe connected them into a a keypad matrix.
