The push button operates a relay or contactor by momentarily completing an electrical circuit. When the button is pressed, it energizes the relay or contactor coil, which closes the corresponding contacts and allows current to flow to the load. Releasing the button de-energizes the coil, opening the contacts and stopping the current. This mechanism allows for remote control of high-power devices using low-power buttons.

How does a normally open contact work?
An electrical switching device that in it's normal rest state does not conduct an electrical current. To become conductive an external force must be applied to change, (switch), it's physical state from open to closed.
How do electrical contactors work?
A contactor is an electrically controlled switch (relay) used for switching a power circuit. an electro pneumatic contactor is similar to the above except it uses a pneumatic signal to initiate the switching of the electric power circuit. an electro magnetic contactor is a contactor driven by an electric control signal. It us usually just called a contactor.
How does a shading coil in a contactor actually work?
A shading coil in a contactor is used to hold the AC contactor's pole faces closed during the transition of the voltage through the zero voltage phase of an electrical cycle.For an excellent description see related links below.

How do you wire a three phase forward - reverse starter?
You start with a normal one way circuit consisting of a three phase contactor and an three phase overload in series for the forward circuit. Then you add the reverse contactor in parallel with the forward contactor but with line one and line two crossed over i.e. when the reverse contactor is made, line one of the supply will be connected to line two of the motor and line two of the supply to line one of the motor. The control circuit must also be interlocked to prevent forward and reverse being energized at the same time.
How relay is used to control induction motor?
If you want to control induction motor using a control relay give neutral directly to the one point of coil of relay & one point of coil of contactor then give control supply through push button to second point of coil of relay. use one NO point of relay and give supply to coil of contactor. and also use one NO of contactor for holding the contactor & take OFF (NC) in the starting to stop motor after complition of work. It is jut like an Direct On-line starter.

How does an auxiliary contact work?
The auxiliary contact is to be utilized for interlocking of another relay or contactor or indication signal from another equipment.

What to check if the horn doesn't work in my 2007 Chrysler minivan?
Start by checking the fuse panel for a blown horn fuse in the fusebox. If it is good, move on to the horn button and relay. The easy way to see if these are working properly, turn the key to "on." There is a horn relay, probably in the fuse box. Push the horn button and listen to the relay for a "clicking" sound. If there is a clicking sound when you push the button, these two should be ok. This should narrow the problem down to the horn itself. I have owned two dodge vehicles and have had to replace a horn on each of them and this was how I determined that it was the horn and not other circuitry.
What do you do if your ipod doesn't turn on?
push the top button and then push the home button. The same thing happened to me it should work hope it works for you too.

Push the snowflake button.....the button has a little light that lights up when you push it so you know it is on....
