The SW7ML-MF is a Surewire pre-wired maintenance free multiple light and switch electrical junction box.

Each model has 2 power in/out connections, a switch connection and a number of light connections.

SW7ML-MF has 7 light connections.

This model is used for downlights where a switch is required. It can be used in conjunction with other Surewire electrical junction boxes or a replacement for current lighting systems. This model can be used to replace a loop-in ceiling rose for downlights.

Main Benefits

  • Easy to wire and maintain
  • Less complicated saving time and effort
  • Reduces the number of terminal connections
  • All connections are cut and stripped to the same length
  • Modular and integrates into any system
  • All cables are strain relieved
  • Can be used in domestic, commercial and industrial premises
  • Rated to 16A 250V
  • Approved to BS EN 60670-22

Other Benefits

  • Surewire is very simple to wire with the circuit pre-determined and clearly marked on the box.
  • Each wire has its own terminal connection which is best practice.
  • Any maintenance or adding additional light switches and light connections is very simple.
  • The lids have recessed areas where stickers or tape can be fixed to identify the light location.
  • Screws in the lid are retainable so you don’t lose them when the lid is removed.
  • The box has cut out tabs so no connection is left open if it’s not being used.
  • Securing holes in the box base are spaced so it can be secured easily to a standard 3” beam.
  • If a light connection is no longer required, simply remove the connection. No rewiring required.

How to install

One cable goes from the consumer unit or power cable from another Surewire junction box to the junction box P I/O connection, one cable goes from the junction box S connection to the switch and cables go from the L connections to the required number of downlights.  If extra downlights are required a Surewire lighting spur junction box can be added to one of the L connections to give extra power outputs.

To integrate Surewire into current systems, isolate the power, locate the lighting radial power cable, cut the cable and wire to both ends of the Surewire junction box at the P I/O connections.  This reinstates the radial power and gives a switch connection and multiple light connections.

To replace a loop-in ceiling rose with downlights, isolate the power and wire the switch and power cables from the loop-in ceiling rose to the Surewire junction box. This gives a number of light connections for downlights.
