The functional reliability of a cable shield system for a high voltage cable circuit is determined by electrically isolating a segment of the conductive shield from ground along the circuit length and supplying a test voltage of gradually increasing amplitude to the isolated shield segment. Current flows in the shield segment and a connected shield voltage limiter (SVL) in response to the supplied test voltage. The current through the SVL is monitored; and the operational integrity of the shield system is determined as a function of the voltage across and the monitored current through the SVL. Current flow is monitored by sensing the heat dissipated by the SVL included in the link box to which the shield segment is connected. Information representing the voltage across and monitored current through the SVL are transmitted to a remote location whereat the operational integrity of the SVL is determined.

A touch module includes a touchpad assembly and a connection assembly. The connection assembly includes a main body, plural first coupling plates and plural protrusion posts. When the connection assembly is accommodated within a computer casing, the plural first coupling plates are penetrated through plural first openings of the computer casing and the plural protrusion posts are inserted into the corresponding fixing structures. The plural protrusion posts and the corresponding fixing structures are collaboratively formed as a hinge structure. While the touchpad assembly is pressed down, the connection assembly is swung relative to the computer casing by using the plural protrusion posts as the pivotal shafts, so that the touchpad assembly is correspondingly swung. Due to the hinge structure, the touchpad assembly is swung along a fixed direction. Consequently, the touch module is operated stably.

A switch device includes an operating knob on which a tilting operation is performed, a detected portion that tilts with the tilting operation of the operating knob, a detection portion that detects movement of the detected portion, and a substrate on which the detection portion is arranged. The detection portion is aligned in an in-plane direction of the substrate and performs a switching operation upon detection of movement of the detected portion in the in-plane direction.

An electrical connector can be provided for connecting a power source to an insertable conductor, including an igniter for exothermic weld material. One or more conductors can be disposed within a housing that is configured to receive the insertable conductor. An actuator can be engaged from outside the housing to move at least one of the conductors within the housing between resting and actuated orientations.

A switch circuit includes a first circuit including a first switch and first output terminals, and a second circuit including a second switch and second output terminals. The first circuit and the second circuit are connected in series. The first circuit has a circuit configuration in which a combination of resistors in a signal path between the first output terminals of the first circuit differs depending on the electrical conduction state of the first switch. The second circuit has a circuit configuration in which a combination of resistors in a signal path between the second output terminals of the second circuit differs depending on the electrical conduction state of the second switch.
