ABSTRACT:
A switch array is defined by a pair of printed circuits separated by a nonconductive spacer which is provided with apertures which form cavities into which switch contacts on the circuits may be forced to produce switch closures. The spacer is contoured to define gas flow channels which communicate with the cavities whereby switch operation will not be impeded by gas trapped in the cavities.
