How to control a lamp from two different places by two ,2-way switches?

By Bharat Ribadiya -


Staircase wiring circuit diagram is very simple. In this given figure staircase wiring circuit diagram is given. By using this, we can control a bulb from two different places by using two, 2-way switches.

Here, you can see that circuit is complete and the bulb is ON. Suppose you want to OFF the bulb from the top of the stair, simply switch OFF the switch which is at the top of the staircase. Now the circuit will break and the bulb will be OFF. You can switch ON to start the bulb again. In other words, you can OFF and ON the bulb from the upper switch at the top of stair or ground switch, below at stair. So let’s see how we can do that from that switch at the bottom of stair or top of the stair. As shown in diagram, the circuit is complete and bulb is ON.

Now you want to OFF the bulb from the bottom switch at the stair. Simply OFF the switch, then the circuit will break and the bulb will be OFF. To turn on the bulb again simply start the switch again.

For turn off the lamp
Conclusion: 

This is a staircase circuit diagram by which we can control a bulb from two different places. We can turn off or on the bulb from both places at the same time. in other words, we can control the bulb from top and bottom switches.

In this article you will learn about how to do three phase wiring in home. Generally, the elctrical supply provider company install single phase energy meter for where requirements is 7.5 kW load in domestic areas but if this limit exceeded then they install 3-phase meter. For this we required following things. Requirements- Required Materials Number Three phase energy meter 1 Three pole, 63 A, MCCB 1 Double pole, 63 A, 30 mA, Trip current RCD 3 Double Pole MCBs, 63A 3 Single Pole, 20A, MCB 6 Single Pole, 16A, MCB 3 Single Pole, 10A, MCB 6 Distribution board cases 3 Cupper strips for MCB Common connection 3 Here, the connected load is single phase. their is no 3 phase load connected to the 3 phase system. The 3 phase wiring are used because our load is more then 7.5 kW. Now, let's start the procedure how to install 3 phase wiring for your home. Figure 1- 3 phase winding in home As shown in the

In this article we learn about how to control a lamp with 3 different switches at different places. This is very useful. For doing this we required two 2-way switch, 1 intermediate switch and a lamp. Connect all these as shown as in the below diagram. Fig.-1 In the above diagram the lamp is on because the circuit is in closed condition.To understand easily the circuit diagram for this, is given below.  Fig.-2 In this case the lamp(bulb) is in off condition. So, the circuit is open condition. Here, one more example is given.  How you can turn on/off a lamp or bulb from six different places. For this we required four number of intermediate switch, two number of 2 way SPDT switch and 1 bulb. Connect all these components as shown as in the figure below. Fig.-3 What is Intermediate switch , its construction and working principle? Fig.-4 An intermediate switch have four terminals. Because of this terminals it is possible to change the flow of the current fro

Automatic UPS system wiring for home or office This article is about how to connect a UPS system in our home or office and this is very useful information.  The below circuit diagram shows the how to connect a UPS from our main supply to appliance(load). This circuit diagram is for in case of falling the main power supply and you want to supply power to specific appliances, TV, AC, laptop etc. in your home or office.  As shown as, two rooms are connected with main power supply.  Here, you don't have to connect the neutral wire connection from UPS because it's already connected the phase and neutral wire from the main power supply with the same point. To connect UPS first you have to remove the connection of phase wire from the main distribution box(from SP,DP or CB) of those rooms which you want to connect with UPS. By doing this(connect with both supply), we can use the power without interruption. If main power fails the UPS will provides the power to the
