A low profile tactile switch including a conductive member having a dome profile and lead means, a conductive contact member having a contact and lead means and an insulating member arranged between the conductive member and the contact member but allowing contact between the members upon actuation of the dome profile, wherein the switch may be mass produced from rolls of flat material.

Low profile tactile switch

A machine and method for making a strip of dome arrays on a backup strip, wherein the dome arrays include a plurality of domes in a predetermined non-linear pattern and in oriented relation to each other that are adhesively mounted on a dome seal. The machine comprises a punch press or stamping machine capable of simultaneously stamping a pattern of domes in non-linear arrangement and oriented relative to each other and depositing those domes onto the adhesive side of a dome seal strip. The machine also includes means for feeding dome seals to the stamping machine and also for kiss-cutting the dome seal while on the backup strip to define a plurality of successively arranged dome arrays.
