Here are the three types of TPS cable commonly used in a two-way switch control system: 1. 2 Core and Earth (2C+E): This cable contains two insulated conductors (typically active and neutral, or active and switched active) and an uninsulated earth conductor. It is used for the main supply to the first switch and for the switched line from the second switch to the light fitting. 2. 3 Core and Earth (3C+E): This cable contains three insulated conductors and an uninsulated earth conductor. It is essential for two-way switching as it provides the two "strappers" (travelers) between the two two-way switches, along with a common active or switched active conductor. 3. 4 Core and Earth (4C+E): This cable contains four insulated conductors and an uninsulated earth conductor. While not strictly necessary for a simple two-way switch setup, it is used in more complex "two-way switch control systems" that incorporate intermediate switches (which allow control from three or more locations).
