There are 2 Surewire pre-wired maintenance free light and switch junction boxes available SW4L-MF and SW2L-MF.
Each model has 2 power in/out connections and a number of independent light and switch connections.
SW4L-MF & SW2L-MF are 4 & 2way pre-wired light and switch junction boxes respectively.
SW2L-MF has been designed for the addition of extra lighting including extensions, conservatories, garages, lofts and outdoor lighting etc.
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 to the junction box P I/O connection, one cable goes from the junction box S connection to the switch and one cable goes from the junction box corresponding L connection to the light. If extra light and switch connections are required, another Surewire junction box can be added in series by using the spare P I/O connection.
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 you extra light and switch connections.
