摘要： A metal-clad isolator switch for multiple interruption divided in two parts insulated from each other and comprising means for connecting the interconnected movable switching contacts of the isolator switch with earth and a selectively operating signalling and protecting system which selectively indicates, when and in which one of the isolator switch parts an unwanted earthconnection occurs.

摘要： A card for simulating peripheral component interconnect (PCI) loads of a computer motherboard uses a PCI interface to be inserted into a PCI slot of the computer motherboard to receive first to third voltage signals from the computer. First to third load modules of the card receive voltage signals from the computer via the PCI interface to simulating first to third power consumption of the computer.

摘要： A disconnect switch has a fixed tubular contact and a tubular contact movable into connection with the fixed contact. A movable auxiliary contact within the movable tubular contact can travel into connection with a stationary auxiliary contact on the fixed tubular contact. The switch has short pre-breakdown times at higher voltages and includes a support shaft carried by the movable tubular contact and at least one sleeve which is arranged on the shaft. A pantograph-like connecting member has one end fastened to the sleeve and the other end coupled to the movable auxiliary contact. Elements of a mechanical control device are also fastened to the outside of the sleeve and, in cooperation with fixed extrusions of the outer switchhousing, cause the sleeve to rotate when the movable tubular contact is moved.
