The single-pole switch on one wire is sometimes very practical in order to add a single light point or a single outlet in a room (except kitchen and bathroom). It used to be the norm, but now you have to be careful how to use it. Its protection in the event of a cut is less important than the bipolar switches meeting all the standards.
Single pole in the right place
Installing a single pole switch requires understanding what it is. Unlike conventional bipolar switches required in humid places or requiring a large amount of energy, the unipolar switch cuts the current only in the phase wire. The other switches interrupt the supply of energy in the phase and in the neutral. This reduced security has advantages, however. Installing a single pole switch on a wire makes it easy to have a control point on a small lamp.
Installing a single-pole switch on a cable: simple and quick
To install a single-pole switch on a wire, simply cut it and connect a simple two-point switch. An olive or a small flat press button can easily adapt to this use. An electric pliers, a screwdriver and a drill in case of wall mounting, are enough to carry out this operation. Installing a single pole switch on a wire can therefore be completed in a few minutes. However, always pay attention to take care to cut off the power supply on the main switchboard.
