dúvida integrating the PS22F02 key switc

[DJordan20999]

Hey everyone,

 

I’m building a custom control panel and added the

for mode selection. It seemed right for the job, but I’ve hit a snag:

The switch activation feels inconsistent, sometimes it doesn’t latch properly when I press it. I’m using it on a PCB with 6 mm trace length from the switch to the MCU pin and the board flexes a bit when mounted. I’m not sure whether the issue is the switch tolerance, poor solder joints, or the fact it’s near the high-vibration environment of a motor housing.

Has anyone used the PS22F02 in a similar application? I’d love tips on soldering technique, pad/footprint layout, or selecting a better variant if this one’s not ideal.

 

Thanks in advance, your advice would really help me get this panel stable!

Several factors were omitted, such as a photo of the bottom PCB, and whether there's a housing and nearby holders from component.

To solve the problem (or just try to), you can increase the tracks on the switch housing, increase a little bit the area of solder, and bend the leads. Try too fiberglass PCB if u can.


 

Use a large GND trace *with*...

Simple ilustration:




Maybe in future, change to a Self-Locking Square Push Button Switch, like these.

I would make a change, using micro tactile switches and their actuations to activate a set of relays for switching, which would get rid of the parasitic vibration from the motor and improve the ease of operating the controls. Of course, it will change something in your code, but it will make its use easier, in addition to the stability and reliability of the assembly. The switch you are using in your project is a mechanical switch and is subject to numerous variations in behavior and failures.
I hope I have helped you in some way, my noble friend.

 

or in this way if needed and if there is space

Good luck.
