Abstract

A switching element that is at least partially implemented in one or more printed wiring boards (PWBs). A first input and a plurality of outputs may be integrated into the PWB(s). In some embodiments, a plurality of contacts may also be integrated into the PWB(s). The switching element is selectively operable in first and second states, the first state in which the first input is coupled to a first output and the second state in which the first input is coupled to a second output.

Description

Background technique [0001] A relay is an electrical switch that opens and closes a conductive path under the control of another electrical circuit. A switch matrix typically includes a plurality of relays used to selectively interconnect electrical paths for routing signals. By opening and closing one or more relays in the switch matrix, conductive paths are created, thereby enabling signals to be routed through the switch matrix. For example, a specific set of relays may be closed to connect a given input to a given output of the switch matrix. Switches are often implemented in test and measurement systems to automate the routing of signals from one device to another. For example, a measurement device (eg, a voltmeter) may be coupled to the output of a switch having multiple inputs, where each input is coupled to a corresponding device under test (DUT). During operation, the measurement device can be used to take measurements from each DUT by sequentially closing the sets...
