A switch including a blade, an electrical terminal, and a sensor. The blade is pivotable between an open position and a closed position. The electrical terminal is configured to receive the blade when in the closed blade position. The sensor is coupled to the electrical terminal. The sensor is configured to sense a position of the blade and output a signal corresponding to the position.

A high voltage vertical break disconnect switch with a planetary gear reduction drive assembly including at least one stage operatively attached to a perpendicular rotatable insulator of the high voltage vertical break disconnect switch. The planetary gear reduction drive assembly includes a lower crankshaft part and a cooperating upper crankshaft part. The lower crankshaft part is solidly connected to the perpendicular rotatable insulator. The planetary gear reduction drive assembly includes an output that drives the upper crankshaft part. The upper crankshaft part drives a movable link assembly that causes a switch blade of the vertical break switch to open and close.

A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.

A system for collecting information related to an electrical switch. The system including a first switch, a second switch, and an external device. The external device is configured to receive the first and second signals corresponding to the first and second switches. Wherein the external device is located remotely from the first switch and the second switch.

In a switch in which one end portion of a blade is pivotally attached to a fixed contactor and another end portion of the blade is brought into pressure contact with a fixed contactor by rotational operation of the blade, at least one slit is provided in each of a conductive contact surface, with respect to the fixed contactor, of the one end portion of the blade and a conductive contact surface, with respect to the fixed contactor, of the other end portion of the blade, so as to divide each of the conductive contact surfaces, thereby achieving multi-point contact on each of the conductive contact surfaces, and a thickness of a contact-pressure spring fixing portion of the blade at which a contact-pressure spring for bringing the other end portion into pressure contact with the fixed contactor is made smaller than that of the other end portion.

A coupling system for securing an elongated rod to a connector that links the elongated rod to a device, and methods therefor, are disclosed herein. The coupling system includes a swivel member pinned in a receptacle of the connector, and a fastener secured to the swivel member. The elongated rod is secured to the fastener. The elongated rod may be a conductor rod and the device may be an interrupter for a circuit breaker.

A knife switch includes a switch housing, a conductive seat, a movable contact part, and a fixed contact part. The conductive seat, the movable contact part and the fixed contact part are disposed in the switch housing. One end of the movable contact part is electrically connected to the conductive seat. Another end of the movable contact part is formed with a conductive head. An outer surface of the conductive head is defined as a first conductive surface. An arc guide hole having a second conductive surface is disposed in the conductive head. The fixed contact part is provided with a contact finger to cooperate with the first conductive surface and an arc guide contact plate to cooperate with the second conductive surface. The knife switch can ensure the normal use of the main current path when the movable contact part and the fixed contact part are electrically connected.

Embodiments of the disclosure can include an inertial short-circuit and seismic hook for an electrical equipment disconnect switch.
