Membrane button for use in paging system, has contact surface contacted during actuation of contact disk with conductive strip, where strip is electrically connected with electric circuit for connection with measuring device

摘要

The button (1) has a contact surface (3) contacted during actuation of a contact disk (2). The contact disk is provided with a conductive strip that is electrically connected with an electric circuit for connection with a measuring device (6). A resistor (5) lies in the electric circuit, and the contact disk is made of springy sheet metal. The conductive strip is provided with a supply segment and a test segment, where the supply segment supplies a voltage potential (U). The resistor is in electrical connection with the test segment.
