    it is a two storey elevator system.....runs by a motor,limitting switches and a simple circuit diagram......this is only my plan and honestly i dont know where to start this project.....so pls help me....thank in advance....

    I assume this is only a project type design. There are probably rules governing the installation of real elevators.

    How complex do you want to make this? Is a simple press and hold the button type? Or do you want a fully automated one that knows exactly where it is at all times? Do you want braking? How about safety catches in case of power failure?

    Let us know a few more details and we can offer a bit more advice.

    How automated? You can have it as simple as pressing a button to go up and it stops when it gets to the top. Do you want it to stop suddenly or slow down as it approaches? What do you expect it to do in case of a power failure?

    As far as w-killa's worry goes for power loss, in an actual working elevator the normal position of the brake is "on". When the elevator starts moving an electric (DC) coil overcomes tension on a spring that is holding the brake on.

    I'm guessing that this is a prototype for a project of some sort. If not, you're in BIG trouble because as killa says, there is a mountain of regualtions and specs involved in certifying and commissioning an elevator.

    Attached a (VERY) over-simplified drawing of a basic elevator lay-out. It does not show things like positive positioning, brake controls, pre-opening, inner- and outer-door controls, VFD or MG motor and motor controls, and a whole host of other things that go into elevator controls and safety. But if you're building a model, this should help you along.

    Hope this helps

    I can't seem to get the attachment to attach. Will try again later. sorry.

    i've finished the circuit already using a number switch(relay,limitting switch,push button).....but my problem is........i want a switch that will automatically close even without pressing it when some unwanted things happen.......

    what exactly do you mean? close, when what unwanted happens?
    maybe you can use a relay - the NC contact.

    Is this some kind of a school project, like a model of an elevator?
