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.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 conductive material into the substrate until the material is substantially flush with the substrate face, and then firing the substrate and conductive material. |
