One way or two way light switch

Electrical switches are very simple devices that are used to turn things on and off. The most common type of switches is the one that we use to turn our lights on and off. Very little has changed in how switches work since when they were invented.

They are wired so that operation of either switch will control the light. One way lighting circuit using in-line switching.

A one way light switch is quite easy to wire up.

Light switch with neutral wires joined fig 2.

The cable going to the light switch is connected as follows (fig ). When the switch is on, both terminals are connected together. This is the most common kind of switch found in . Typically, these terminals will be marked COM. They can also be used when there are two switches for one light.

These diagrams show various methods of one , two and multiple way switching. Note that Land Lare never connected together. Switches are shown as dotted rectangles. Again, some makes of switch may have alternative markings such as LLand L3.

The diagrams here are all one gang, as there is one switch on each plate. The switches themselves are one way , two way and intermediate. Home systems have some strange terminology.

The common is the main live coming in. The Lis the switched live going out to the light. They will be marked so you can tell which is which.

Two way switch (UK light switch ). Wiring details for one way lighting circuits as used in the UK. As described on the other pages, the two switch wires are both live. Jamme as in would not turn either way , and the head slot broke open in the attempt. Be cautious when opening up multi- way switches.

The lights they control should take power from the same circuit , but if yours are incorrectly wired and take power from different circuits, there will be live cables at each switch position when one circuit is isolated. This two way light switch can be wired to the majority of household lights. There is more than one method of wiring multi- way lights. Rated between 60W and 400W, the dimmer action allows you to set lower lighting levels for movie .
