Switch Class
A generic device designed to close, or open, or both, one or more electric circuits. All switches are two terminal devices including grounding switches. The ACDCTerminal.connected at the two sides of the switch shall not be considered for assessing switch connectivity, i.e. only Switch.open, .normalOpen and .locked are relevant.

| SvSwitch | SvSwitch | The switch state associated with the switch. | 0..n |
| normalOpen | Boolean | The attribute is used in cases when no Measurement for the status value is present. If the Switch has a status measurement the Discrete.normalValue is expected to match with the Switch.normalOpen. | 1..1 |
| ratedCurrent | CurrentFlow | The maximum continuous current carrying capacity in amps governed by the device material and construction. The attribute shall be a positive value. | 0..1 |
| retained | Boolean | Branch is retained in the topological solution. The flow through retained switches will normally be calculated in power flow. | 1..1 |
| SwitchSchedules | SwitchSchedule | A Switch can be associated with SwitchSchedules. | 0..n |
| open | Boolean | The attribute tells if the switch is considered open when used as input to topology processing. | 1..1 |
| locked | Boolean | If true, the switch is locked. The resulting switch state is a combination of locked and Switch.open attributes as follows: <ul> <li>locked=true and Switch.open=true. The resulting state is open and locked;</li> <li>locked=false and Switch.open=true. The resulting state is open;</li> <li>locked=false and Switch.open=false. The resulting state is closed.</li> </ul> | 1..1 |

| cim:Cut |
A cut separates a line segment into two parts. The cut appears as a switch inserted between these two parts and connects them together. As the cut is normally open there is no galvanic connection between the two line segment parts. But it is possible to close the cut to get galvanic connection. The cut terminals are oriented towards the line segment terminals with the same sequence number. Hence the cut terminal with sequence number equal to 1 is oriented to the line segment's terminal with sequence number equal to 1. The cut terminals also act as connection points for jumpers and other equipment, e.g. a mobile generator. To enable this, connectivity nodes are placed at the cut terminals. Once the connectivity nodes are in place any conducting equipment can be connected at them. |
| cim:ProtectedSwitch |
A ProtectedSwitch is a switching device that can be operated by ProtectionEquipment. |
| cim:Disconnector |
A manually operated or motor operated mechanical switching device used for changing the connections in a circuit, or for isolating a circuit or equipment from a source of power. It is required to open or close circuits when negligible current is broken or made. |
| cim:Fuse |
An overcurrent protective device with a circuit opening fusible part that is heated and severed by the passage of overcurrent through it. A fuse is considered a switching device because it breaks current. |
| cim:GroundDisconnector |
A manually operated or motor operated mechanical switching device used for isolating a circuit or equipment from ground. |
| cim:Jumper |
A short section of conductor with negligible impedance which can be manually removed and replaced if the circuit is de-energized. Note that zero-impedance branches can potentially be modelled by other equipment types. |
