High tech keyswitch assembly jig300 viewsI then just added the PCB and soldered the 2 pins at the right. To ensure both pin collars were hard up against the board, I used a screwdriver to apply pressure to the centre of the board and just remelted the solder. The 3rd pin is not soldered, it just helps to hold the board in position

Completed keyswitch287 viewsI used the keyboard frame to temporarily hold each switch vertical while the adapter board was attached, using the same solder/ screwdriver pressure/remelt technique to ensure a tight PCB fit to the keyswitch base
