This is for a tactile combination scroll wheel & pushbutton assembly. TSW Switch This switch includes a quadrature encoder for rotary as well as several buttons for up, down, left, right as well as a center Enter button.
I am making a pcb for the above schematic. S1,A,B go to COM A and S2,S3,S4,S5 go to COM B but all 7 each are going to have different functionalities when they are clicked but they are grouped in a set of 3 and a set of 4. As a thru hole pcb do I have 7 hole for each or just 2; one for COM A and one for COM B. having 2 seems to be what the schematic is showing.
My question is though, if I only have holes for COM A and COM B, how will it differentiate that S2,S3,S4,or S5 was clicked in COM B or S1,A,or B was click in COM A
But if there are thru holes for all seven then I can easily tell which one of the seven was clicked but that doesn't seem to follow the schematic.
Any insight is much appreciated. I'm am very new to electrical engineering and am a hobbyist so let me know if I didn't explain something correctly or if more information is needed to answer my question. Thanks - Jeff
