What's the distance between my keypad and PCB, if I use your circle metal dome array?

Normally if you use our C series, 4mm or 5mm metal dome to make double layer dome array, then the total thickness of whole dome array is about 0.27~0.30mm+/-0.03mm, various upon different force. The higher force dome is, the higher height dome array will be. Please contact us for more details about dome array, if you use other Shapes ( FTO series) and force.
