The invention relates to a switching device including a housing having a front housing and a rear housing. The rear housing includes a rear housing face, and a first sidewall, first end a second sidewall, and a second end wall projecting from the rear housing face to form at least one interior chamber. The sidewalls of the rear housing include a rear housing tab that projects away from the rear housing face. The switching device further includes a splitter plate support, comprising first and second support panels, located within the interior chamber. The first support panel further includes a support hook that extends from the outer panel face. The support hook has an aperture that engages the rear housing tab, in which the rear housing tab extends through the aperture of the support hook, forming a double-walled panel and reinforcing the housing.

A power supply system includes a control unit, a switch, a direct current source, and a power change unit. The switch includes a switch unit and an operation mechanism. The operation mechanism is configured to receive a switch-off signal and control the switch unit to be turned on or off. The switch unit includes a first static contact, a movable contact, and a first arc extinguishing structure. When the switch unit is turned off, the movable contact rotates about a rotation center relative to the first static contact by a first included angle to be separated from the first static contact, to generate a first arc. The first arc extinguishing structure includes a first arc extinguishing end part and a second arc extinguishing end part. A connection line between the first arc extinguishing end part and the rotation center of the movable contact is a first line.

A changeover switch for medium voltage switchgear is provided. The changeover switch includes a first terminal body, a second terminal body, and two elongate pole bodies. The two elongate pole bodies are arranged parallel to each other and rotatably arranged with first ends on opposite sides of, and in direct contact with the first terminal body around a rotation axis. The two elongate pole bodies are rotatable between an open position and a closed position. The second ends of the two elongate pole bodies are positioned in direct contact with opposite sides of the second terminal body. The changeover switch further includes one or more springs arranged between the two elongate pole bodies to urge the two elongate pole bodies towards each other.

A controlling device has a moveable touch sensitive panel positioned above a plurality of switches. When the controlling device senses an activation of at least one of the plurality of switches when caused by a movement of the touch sensitive panel resulting from an input at an input location upon the touch sensitive surface, the controlling device responds by transmitting a signal to an appliance wherein the signal is reflective of the input location upon the touch sensitive surface.

Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.
