An interlocking system for a circuit breaker assembly including a circuit breaker having a plurality of contacts includes a racking screw coupled to the contacts that changes a position of the circuit breaker when engaged by a tool. The interlocking system also includes a front panel defining an opening through which the racking screw is accessible, an access door coupled to the front panel and configured to selectively cover the opening, and an access door stopper coupled to the front panel. The interlocking system also includes a trip assembly coupled to the access door stopper. Each of the access door, the access door stopper, and the trip assembly are moveable between a first position and a second position such that moving to the first position triggers delivery of a trip signal to the circuit breakers to open the plurality of contacts, and wherein, in the second position, the access door is fully open to enable access to the racking screw through the front panel.

In a first aspect of the present disclosure, a push switch includes a substrate including a first electrode and a second electrode that are arranged on an upper surface of the substrate; a resilient member arranged on the first electrode over the second electrode of the substrate; and a light-transmitting member including a crosslinked product of a chain olefin-cyclic olefin copolymer. The light-transmitting member covers the resilient member from above and includes an upper surface, a lower surface, a peripheral side surface between edges of the upper surface and edges of the lower surface of the light-transmitting member, and a periphery of the lower surface of the light-transmitting member. The periphery may be fixed on the substrate.

A monitoring method for an electrical energy transfer device which has a first phase conductor and a second phase conductor, includes the following steps: a temperature of the first phase conductor is compared with the temperature of the second phase conductor and a signaling is performed if there is a deviation between the temperatures. The electrical energy transfer device is, for this purpose, equipped at the first phase conductor with a first temperature sensor and at the second phase conductor with a second temperature sensor.

An arrangement includes a gas insulated switchgear and a RC voltage divider. The gas insulated switchgear includes a switchgear compartment and a voltage divider compartment. The RC voltage divider and the gas insulated switchgear together at least partially form a hermetically sealed common gas compartment. A method for assembling the arrangement is also provided.

A sensor device includes a body case provided with an opening, and a body cover assembled to the body case to cover the opening. The body cover has at an outer peripheral portion thereof an overlapping region overlapping a portion of the body case located at a peripheral edge of the opening. The body cover is fixed to the body case by providing a welded portion surrounding the opening using laser-welding at a portion distant from an end surface of the body cover in a boundary of the overlapping region of the body cover and a portion of the body case overlapping the overlapping region.

Systems and methods for providing a replacement touchless button for initiating an action upon proximate detection of a solid object near the top of the touchless button. The action is triggered by determining that the solid object is within a predetermined distance from the top of the button. The action is accomplished by the closing of an electrical circuit within the touchless button, the button being configured to replace a push button without modification of a panel housing the push button. The button contains and supports, within its structure, all electrical and physical components needed to operate a device that can be triggered via a push button. The button serves as a direct replacement for a push button with no modifications to existing systems or controls regularly triggered by a push button.
