It is time to change the switch for a new one. Switches only last so long being turned on and off on a daily basis. Their mechanical parts get worn and the internal blades that open and close the circuit get loose. Time for a new one. Shut the power off at the breaker and exchange the wire positions one at a time to exactly the same position on the new switch.
What else can I help you with?
What if your switch is on but the bulb is off?
There could be a series of problems. First, are all the wires hooked up? Is the bulb burned out? Is it just the switch that is not working? You should go and put in a new bulb, and see if it was just burned out.
If a light bulb is burned out and the switch is on are you still using electricity?
A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it. If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on It may still use power if it is a lighted switch. Find a licensed electrician at www.contraxtor.com
There is two rooms one has three light bulbs in it the other has three switches you are only allowed in the first room once you start in the secon how do you find out which switch operates which bulb?
You turn on two switches wait 5 min. and turn one of the switches off! go in the next room the cold one belongs to the switch you never turned on..the warm one the switch you only left on 5 min and the lite one to the switch that is turned on! you switch on one switch for a few minutes, one for ages, and dont turn the other one on at all. you go through to the other room, the bulb that is warm is operated by the first switch, the roasting hot bulb (that would burn your hand) is operated by the second switch, and the cold bulb is operated by the third switch.
What circuit do you need for two switches one bulb?
wiring diagram of one bulb in two switches.. example, if switch a- on then switch b- off the bulb is on, switch a- off then switch b- on the bulb is on, switch a- on then switch b- on the bulb is off, switch a- off then switch b- off the bulb is off..
You are in a room that has 3 switches and a closed door The switches control 3 light bulbs on the other side of the door Once you open the door you may never touch the switches again?
Turn on one light and leave it on for a little while then turn it off. Turn the next light on and open the door. Go up and feel the light bulbs..the warm one is the first loth switch,, the one that is still on is obviously the second light switch and the cold/regular temperature light bulb is the last switch that you didn't touch.
When you open the switch what happen to the bulb?
If the switch is in the off position, the circuit will be broken and the electric current can't flow to the bulb, so the bulb will not light up.
Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
How can you make a light bulb go off when a door is opened?
Use a normally closed (NC) contact switch rather than a normally open (NO) momentary contact switch.
Why does the bulb not light up until you press the switch?
the bulb will light up when current flows thru it if the switch is open no flow will take place
Why is a light bulb not on when a switch is not closed?
A closed switch completes the electrical circuit, allowing current to flow through the light bulb and generate light. If the switch is not closed, there is an open circuit, meaning the current cannot flow and the light bulb does not turn on.
What could you add to the circuit to control the bulb?
Switch
Why do you have to close the switch to make the torch turn on?
Closing the switch in a torch completes the electrical circuit, allowing current to flow from the battery to the bulb. When the switch is open, the circuit is broken, preventing electricity from reaching the bulb and keeping it off. By closing the switch, you enable the flow of electricity, which powers the bulb and turns the torch on.
What describes electricity flowing from a battery though a switch to a light bulb?
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
What bulbs glow when switch A is closed and switches B and C are open?
it's bulb 3
How does removing a bulb or opening and closing the switch affect a parallel circuit?
it is because the energy flows through the switch and it makes the light bulb turn on and if the switch is open the energy will not flow it will stay in the place the switch begins
If lamp switch is ON and if you remove the lamp bulb we still wasting electrict?
no because when you remove the lamp the circuit is still open; even if the switch is on
How do you make a simple electric bulb go out?
Usually it is by pushing the switch on the wall into the down position. If that does not work, turn the bulb until it does not make contact and fix the switch.
