deskthority

This keypad is from an old machining center (lagunamatic something). I pulled this when the machine was being scrapped over a year ago. Finally got around to looking at it and I cannot find this mount type (still fairly new at keyboards so I could be just dumb). The back of the board says KeyTronic but its not their foil stlye.There isn't much info I can find about their non keyboard products. I think it may be a linear switch but, I'm not great at identifying between linear and older membrane hybrids.
