Title:
ELECTRICAL SWITCH DEVICE AND PROCESS FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO2001022437
Kind Code:
A9
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. 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.
