These switches are not expensive so used in simple circuits. This kind of switch is used where there is a requirement of two switches to switch off a single light. For example in a hallway, one switch is used at the base of the stairs whereas another one is used at the top. The connection of this switch is shown below and it can be used as a one-way switch. This switch is very versatile and it is used where three switches are necessary to control a single light.

It is expensive to compare with others. When you have three switches to control a light , then the center switch must be intermediate. An intermediate switch symbol is shown below. A final question we often get asked. Why does it cost so much more? Well the answer's simple. It is a more complicated circuit see the illustrations above and therefore costs more to manufacture.

What is an Intermediate Switch? Read Below for More Details on the Various Switches Available An intermediate switch is only used on certain occasions so first of all let's cover the other switches and when you'll need them. In Fig 3, a lamp is controlled from three different places by using two, 2-way switches and one intermediate switch. Below is the same diagram Fig 4 to control a light point lamp from three different places by using two, two-way switches and one intermediate switch with different symbols.

Below is a given schematic circuit to control a light point from three different places by using two 2-way switches and intermediate switch in the middle of stairs. In fig 5, a lamp is controlled from six different places by using two, 2-way switches and four intermediate switches.

Key Point: You may control a lamp from many different places by adding more intermediate switches such as in the middle of stair or in shared flats when needed. Also, many other electrical appliances like fans, alarms, machines etc can be control from different places by using intermediate switch. Also read:.
