Electricity Transmitter and receiver. is there anything such as that. Answered

Electricity Transmitter and receiver. is there anything such as that. simple though. when i press a button it transmits a signal and the receiver receives this signal and releases electricity. heres a little diagram:

O------T             B-R-----M

O=Button
T=Transmitter
R=Receiver
B=Battery
M=Button
-=Wire
 =Air?

the receiver is powered by the battery

To add to what others have already posted...

If your wanting to charge a battery wireless, that is called inductive charging. While you don't have to plug a cord into the battery you pretty much have to have it sitting right over the charging pad.

You can find instructables on how to make your own inductive charger or you can buy one. The commercial systems will have sleeves for your phone or other devices to adapt them for inductive charging.

Yep, its called a radio. A transmitter broadcasts radio waves, an antenna receives them and converts the wave to electrical energy. The stronger the transmitter and receiver are the more powerful the electrical current is. Unfortunately, the energy output to input is incredibly low.

Do you mean something like a wireless way to turn a battery or ultra cap on and off?

The remote on your TV is powered by a battery, it transmits a signal, which the TV receives, which in turn opens a switch and electricity flows through the TV's circuits. Of course you could replace the mains line with a battery to be closer to your original description.
Or...
Are you talking about a way to generate electricity on one end and transmit it wirelessly? The only way I know of to do this SAFELY at normal currents and voltages is with inductance. MIT was (I'm not sure of the current state) working on a whole room resonant inductive charger that could power most everything in a small room from the lights to a cellphone.
