Another push button mod

Martin All Messages By This Member #3863 Edited Hi All, I got fed up with the Jog wheel sticking, so today I took the plunge and fitted some PCB mount push buttons behind the front panel (see attached). The wiring is the same as the push button mod in the files section. I simply drilled some small holes in the PCB front panel and attached the buttons to the rear. There is just enough space and depth between the panels for the miniature switches to fit nicely in place. The top of the buttons are flush with the surface of the PCB, but it's easy to operate them with the edge of your thumb nail. I insulated the back of the switches so that they can't short against the other PCB, and ran the thin connecting wires between the PCB panels through the newly vacated Jog wheel mounting holes. I also cut down the slider of the rather delicate miniature on/off switch, so that it doesn't accidentally get caught on other objects or become switched on in transit.

Martin All Messages By This Member #3872 I got the switches off a scrap set top box PCB, but you can buy them almost anywhere. They are 6mm x 6mm and come in a variety of button heights. 4.3mm is flush with the PCB, 7mm sticks out slightly, take your pick. -- Regards, Martin - G8JNJ
Larry Rothman All Messages By This Member #3877 Yup - been telling folks here for months about how they can get 'free parts' from all the old stuff they have lying around. That's what this hobby is all about - hardware hacking and having fun doing it! toggle quoted message Show quoted text On Thursday, October 3, 2019, 2:14:06 p.m. GMT-4, Martin via Groups.Io <martin_ehrenfried@...> wrote: I got the switches off a scrap set top box PCB, but you can buy them almost anywhere.

Shirley Dulcey KE1L All Messages By This Member #3979 If you ever bought one of the popular starter kits for microcontrollers like Arduino, it probably contains some suitable switches. I bought a bag of assorted varieties of these switches from Banggood so I could try out the various form factors, especially the length of the button: In that assortment they are about 3 cents per switch. If you need a bunch of a single type, you can buy bigger bags of them and they are even cheaper.
[email protected] #4310 Is this the same switch assortment?

Roy Appleton All Messages By This Member #4312 Looks like it to me! Just double the price but you can get them in 3 days not 3 or 4 weeks! ?
