Electrical switch device and process for manufacturing same

TL;DR: In this paper, a method of manufacturing a thick film switch element includes providing a low temperature co-fired dielectric substrate in a green state, depositing an electrically conductive material onto a face of the substrate, pressing the conductives material into the substrate until the material is substantially flush with the substrate face, and then firing the substrate and conductive materials.

Abstract: An electrical switch device includes a thick film switch element having a low temperature co-fired dielectric substrate, electrical conductor tracks embedded in the substrate and having a surface substantially flush with the substrate surface, and wiper contacts in sliding engagement with the conductor tracks. The switch is useful for position sensors, throttle controls, and digital encoders.
