A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

A busway system including a first electrical busway section, a second electrical busway section, the first and the second electrical busway sections being offset from each other, a busway joint for coupling the first and the second electrical busway sections. The busway joint including a plurality of busbars, a plurality of splice plates electrically coupled to the plurality of busbars, the plurality of splice plates and the plurality of busbars configured to electrically couple the first and the second electrical busway sections, and a pivot shaft passing through the plurality of busbars and splice plates.

A switch assembly, a system, and a method are provided. One such switch assembly includes a first connection bus to connect to a power source or a load and a second connection bus to connect to one of a second power source or the load. The switch assembly includes a shaft, a driving mechanism to engage the shaft, and a toggle arm connected to the first connection bus and secured to the driving mechanism. The switch assembly includes a pivot arm electrically connected to the second connection bus and including a contact pad. The shaft is structured to rotate the toggle arm from a closed position to an open position by rotating the driving mechanism, and in the closed position, a contact pad of the toggle arm contacts the contact pad of the pivot arm. The pivot arm is maintained substantially parallel to the second connection bus.

A fuse device comprising a housing, at least two connection lugs, a connecting element between the connection lugs, and an actuator. The actuator moves the connecting element from a closed position, in which it connects the connection lugs, to an open position, in which it is disconnected from at least one of the connection tabs. A particularly well-conducting connection between the connection lugs and the connecting element, which can nevertheless be easily disconnected by the actuator, is achieved by the connecting element being interference-fitted between the connection lugs.

A switch device according to one or more embodiments is disclosed that may include a pressing member, an urging member, fixed contacts, at least one movable contact swingable in a direction intersecting with a movement direction of the pressing member and connecting and disconnecting between the fixed contacts.

The pressing member includes a slider portion extending in a direction oblique to the movement direction and slidable along the movable contact. The movable contact is pressed by the slider portion in the pressing member sliding to swing and come in contact with and separate from at least one of the fixed contacts in response to the pressing member moving from a reference position to a pressed position.

A switch includes a base; switch parts having a common fixed contact and a first and a second fixed contacts; a slide body having a second movable contact configured to be in contact with the common fixed contact and a first movable contact electrically connected to the common movable contact and configured to be in contact with the first and the second fixed contacts, the slide body rotatably supported by the base; a cover mounted to the base; an operation lever supported by the cover to rotate the slide body; and a reverse spring which biases the slide body and the operation lever to be close to each other. The first movable contact slides to be in contact with or separate from the first and the second fixed contacts, and the second movable contact slides while in contact with the common fixed contact, by rotation of the slide body.

A switch includes a power in contact, a piston, a power out contact, a plurality of flexible locking elements, an earthing contact, and a threaded rod. In a first position, the piston contacts the power in contact and the power out contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the earthing contact and the power out contact. The piston comprises an inner threaded section that engages the threaded rod. Rotation of the threaded rod moves the piston along an axis of the switch between the different switch positions. The piston comprises a groove extending in a direction parallel to the axis. Each of the flexible locking elements is configured such that a part of each of the flexible locking elements moves into and out of the groove as the piston is moved along the axis of the switch.

The pool water level and vacuum monitor is a device that is adapted to be seated on a pool deck adjacent to a swimming pool, and which monitors water level when filling a pool liner whilst a vacuum is removing air from behind a pool liner and a concrete wall of a pool. Moreover, the pool water level and vacuum monitor includes a telescoping armature that extends aside of a housing. The telescoping armature includes a cord and a float member on a distal end of the cord. The float member is adapted to rest on a pool surface of the swimming pool, and moves to close a float switch integrated in the float member. The float switch is able to turn off all circuitry associated within the housing.
