A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has a second conductive layer protruding from the bottom layer top surface and spaced apart from the first conductive layer. The conductive member is rollably disposed in the chamber and is limited by the second conductive layer for forming a current path with the first and second conductive layers.

A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The bottom layer assembly has a bottom groove communicating with the chamber. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has at least one second conductive layer disposed in the bottom groove. The conductive member is rollably disposed in the chamber for forming a current path with the first and second conductive layers.

A switching element that is at least partially implemented in one or more printed wiring boards (PWBs). A plurality of inputs and a plurality of outputs may be integrated into the PWB(s). In some embodiments, a plurality of contact bars may also be comprised in respective contact bar pockets bounded at least partially ab at least one of the PWB(s). The switching element is selectively operable in first and second states, the first state in which at least one contact bar couples one of the plurality of inputs to one of the plurality of outputs such that an analog signal input to the respective input is routed to the respective output and the second state in which at least one contact bar is held in an off state.
