I built a midi controller using a 50s hammond 12 key foot keyboard. However the factory switches used these plastic pushers and after 60 years the plastic is breaking down and many of the switches no longer engage. I am taking it as an opportunity to shed 5 or 6 pounds and a bunch of lead solder by loosing the entire switch assembly

Im seeking advice / opinions on what I should use for switches. Im thinking the easiest thing would be getting some panel-mount momentary switches and mounting them on a bar so they get pressed when the key goes down. But then I was thinking about the pressure switches so I could do something with key-specific volume. ideas? cost is a factor...

Thanks
