A cube fuse adapter (1) comprising an adapter housing (2) shaped in the form of a cube fuse and including a pair of fuse reception contacts (4-1, 4-2) provided to receive a cylindrical fuse (5), wherein both fuse reception contacts (4-1, 4-2) are connected to associated electrical contacts (3-1, 3-2) protruding from a bottom side of the adapter housing (2) of said cube fuse adapter (1).

An example polarity inverter includes multiple contactors, each of which includes switches that are controllable to configure a current path. Each of the multiple contactors includes contacts, which are interleaved such that first contacts to receive voltage having a first polarity alternate with second contacts to receive voltage having a second polarity, where the first polarity and the second polarity are different. The polarity inverter also includes a first conductive plate to connect electrically to each of the first contacts, and a second conductive plate to connect electrically to each of the second contacts. The first conductive plate and the second conductive plate are in parallel. A dielectric material is between the first conductive plate and the second conductive plate.

An electrical switching device, such as a high-speed switching device, has a damper and latching assembly. The assembly is configured to dampen the movement of a moving contact of the switching device as the moving contact translates from its closed position to its open position. The assembly also is configured to restrain the moving contact in its open position. The assembly stores at least some of the energy associated with the damping process, and uses the stored energy to assist in the release of the moving contact during the subsequent re-closing of the switching device.

A radio frequency switch connector includes: a metal case; an insulator defining an inserting hole and received in the metal case; an elastic terminal retained to the insulator and having a first soldering portion; and a fixed terminal retained in the insulator and having a second soldering portion, wherein the first soldering portion and the second soldering portion are aligned with each other in a first direction so as to define an imaginary center line in the first direction, the base of the outer case is asymmetrical at two sides of the imaginary center line so as to shift a weight of the radio frequency switch connector.

A circuit board enclosure comprises a circuit breaker, platform, base, cover, and circuit board. The circuit breaker includes two conductors and a plate, which is connected to the conductors. The platform receives the circuit breaker. The base has a bottom member and an opening arranged in the bottom member. The base receives the platform with the circuit breaker such that the plate of the circuit breaker is accommodated substantially within the opening of the bottom member. The cover is configured to cover the base and form an interior space. The interior space accommodates the platform, the circuit breaker, and the circuit board. The circuit board is connected to the circuit breaker. The circuit board enclosure can be adhered to a substantially planar surface. The plate is configured such that removal of the circuit board enclosure from the substantially planar surface will damage the connection of the plate to the conductors.

A switch includes an actuator for moving the switch from an OFF position to an ON position. A resistor is connected in series between a first terminal and a second terminal, and limits inrush current that flows when the switch is moved from the OFF position to the ON position.
