Electrical Wiring - How to Wire a Light Switch In this video we look at a lighting circuit using the 2 plate method and I explain the connections within a one gang 1 way switch. The 2 plate method takes the feed (supply) to the switch and is often used in installation that have lots of downlights fitted (LED) because it reduces the number of cables at the lighting points.. Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E. #GSHElectrical
