Abstract
An improved device for testing electrical circuit tracings on a printed circuit board is provided. The device includes a first plate, a second plate and connecting elements for connecting the first and second plates to one another, such that one or both of the plates can be moved relative to one another such that one or both of the plates can be moved relative to the other between a distal position wherein the plates are distal to one another and a proximal plate position wherein the plates are proximal to one another. The device further includes retaining device, which preferably is a pull-out tray, for retaining a printed circuit board between and substantially parallel to the first and second plates and a plurality of test probes disposed either above the retaining device and/or below the retaining device. The test probes are disposed so as to contact a trace on a circuit board being tested when that circuit board is disposed on the retaining device and when the plates are in the proximal plate position. The connecting elements include a motor operatively connected to at least one of the plates by a pair of horizontally slidable cam bars which are attached to at least one of the plates by a cam follower connection. By this configuration, the operation of the motor causes movement of at least one of the plates between the distal and proximal plate positions.
