Flex7 Switch Drop Lead is pre-stripped and ferruled tails provide easy on site termination to a switch, the other end simply plugs into the switch drop port of a control pack. Whether linking sensor heads or switches to the Control Pack there is a complete range of different length leads to choose from. To avoid confusion, leads are colour coded grey for Sensor Head linking, and blue for Switch Drops and Switch Drop Adaptor linking. Remember that all flex7 controls operate at PELV, so using our Switch Drops, unlike mains voltage switching, means that cables can be set at any depth within the wall, will not require enclosing in an earthed metallic covering nor will the circuit require the added protection of an RCD for that purpose.
