Abstract:
An electrical switch device having at least two electrical conductors engageable by a wiper contact slidable over said conductors, made by the process of:(a) providing a low temperature co-fired dielectric substrate in a green state; (b) depositing an electrically conductive material onto a face of said substrate to form said electrical conductors; (c) pressing said electrical conductors into said substrate until said conductors are substantially flush with said substrate face; (d) after step (c), firing said substrate with said flush electrical conductors at a temperature sufficient to sinter said substrate but less than the melting point of said electrical conductors, wherein said electrical conductors and said substrate have a similar shrinkage during firing such that after firing said electrical conductors are substantially flush with substrate surface; and (e) assembling the electrical wiper in sliding engagement with said conductors.
