This is a 6x6mm reverse mounting tactile button surface mount type for some special PCB design. We make the pins upside down .The Actuator height off PCB is customizable. What we have now is 6.5mm height and 4.5mm mounting height. Please look at drawing as below. If you have a 1.6mm thick PCB, the button top will rise 0.4mm over PCB. And if you have a 0.8mm thick board, it would rise 1.2mm over PCB.
