before you begin with the work,  you should absolutely, which most important safety rules consider      As a switch circuit in the electrical installation is a circuit with switches and relays. A typical application is the switching on and off the lighting in stairwells and long corridors.     In general, a switch circuit used when the circuit by many or from distant places to be served. In their flow of electricity load on the Controls, but a short way directly to consumers. The minimal electrical resistance losses are avoided. The parallel switch reduces all the effort in the wiring. The circuit can all be operated from buttons. The relay will be mounted in distribution, including the fuses.     There are two types of circuits button distinguished:     Electric circuit   The bi-relay for this variant are considered current surge switch. If no button is pressed, and then any button is pressed, the current surge switch a voltage pulse, the result of the electromagnets it contains a power surge. The electromagnet operated the break. The Contact engages in both mechanical switch. Each new voltage impulse leads to interaction between the two switching status.   Staircase circuit   The time for this relay also stairwell-time circuit called variant as staircase machines or stair light machines. All buttons can be turned on. After a stairwell at the time adjustable machines that automatically switches off. The buttons can not be switched off. In high staircase machines can also "buttons again" buttons it again before the lights off, then begins the time the machine again.           To test the completed circuit wired you go easy steps:     with electric shock switch press each button once to turn and then immediately again to back off.     staircase with machine it is best if you at the stairwell near the time setting down adjust  then does it not so long. touch the first button and wait until the light turns off. If the test works is the next button and the next .... If all has gone you do when your machine staircase desired time and finished!
