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
