Use of flex switches

It can be useful to install a switch in the flex of some small appliances to make it easier to operate. A common use is in the flex of bedside lamps.

Never use a flex switch where it may be possible for it to come into contact with water. They are not suitable in kitchens for example.

Switch off the mains socket outlet and remove the plug of the appliance.

Preparing the flex switch

Release the retaining screw on the new switch and remove the cover. Inside you will see a rocker type switch with a terminal at each end, and a clamp for the flex at both ends of the unit.

Preparing the flex

Prepare the flex by carefully making a slit in the outer sheathing taking great care not to cut into the insulation of the conductors. The length of the slit should be a little less than the distance between the flex clamps. Peel back and remove this section of sheath.

Cut the live, brown conductor midway along this exposed section. Strip the ends back by 1/2" and, taking each end in turn, twist its separate filaments.

Connecting the flex to the switch

Connect one to each side of the switch using the small terminal connectors provided.

Note that the neutral, and earth (if you have one), do not get cut since they run straight through uninterrupted.

Secure the flex at both ends in the small clamps to prevent strain on the connections.

Double check you work and then replace the cover and fasten the retaining screw.
