Definition from IAI: An IfcSwitchingDeviceType defines a particular type of switch which is a mechanically operated contactor.

> HISTORY: New entity in IFC 2x2

Use Definitions

An IfcSwitchingDeviceType is a subtype of IfcFlowControllerType that provides for all forms of switch.

Usage of IfcSwitchingDeviceType defines the parameters for one or more occurrences of IfcFlowController. Parameters are specified through property sets that are enumerated in the IfcSwitchingDeviceTypeEnum data type.

Property Set Use Definition:

The property sets relating to the IfcSwitchingDeviceType are defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcSwitchingDeviceType are part of this IFC release:

- Pset_ElectricalDeviceCommon: property set for properties that are common to all types of electrical devices, if available
- Pset_SwitchingDeviceTypeCommon: property set for properties that are common to all types of switching device, if available
- Pset_SwitchingDeviceTypeContactor: specific property set for the properties of a contactor , if available
- Pset_SwitchingDeviceTypeEmergencyStop: specific property set for the properties of an emergency stop device, if available
- Pset_SwitchingDeviceTypeStarter: specific property set for the properties of a starter, if available
- Pset_SwitchingDeviceTypeSwitchDisconnector: specific property set for the properties of a switch disconnector, if available
- Pset_SwitchingDeviceTypeToggleSwitch: specific property set for the properties of a toggle switch, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
