I am designing a PCB, and it needs to have a right angle tactile switch. I am going to use a through hole, since it should offer added strength compared to a surface mount.
I am looking at the data sheet of this switch: Datasheet PDF
Looking at the schematic, pin 1 and 2 are the switching pins. It doesn't specifically say which pins are 1 and 2 however. From past knowledge, I assume those pins are the two inner ones.
Assuming I am correct, the outer pins just connect to each other, to add strength to the switch. Is it best practice to solder them both to the ground plane? Or just have an unconnected copper trace for them? Or just a hole, and leave them unsoldered?
