I have a motorised shutter and I need to buy a in-wall switch to automatically stop when the shutter reaches the floor or the ceiling by only one push and not keep holding the switch.

Hello, and welcome to Stack Exchange. More details would be helpful, e.g. the manufacturer and model of the shutter motor. (And, what's a "selling boy"; do you mean "ceiling"?) – Daniel Griscom Mar 29 '16 at 13:05

2The shutter motor (door opener) you buy should come with these attributes or have the facility to be programmed for this behavior. – ArchonOSX Mar 29 '16 at 13:30

correction yes the celling flour. – Hussein Shehab Mar 30 '16 at 11:19

You'll want a controller circuit then, so a pulse will activate the motor going down and will deactivate when a limit switch has been activated or the button has been pushed again (using another button for going up). The design of such a circuit is out of scope on this SE.
When you do install such a controller circuit make sure the relays for driving the motor are rated for its power.

1You'll also need all the safety sensors that typical garage doors have (obstruction detection, collision detection, etc.). – Tester101 Mar 29 '16 at 12:39

@Tester101 "shutter" can also mean window shutters or automatic curtains. – ratchet freak Mar 29 '16 at 12:46

I agree, but the OP says "*reaches the floor or the selling*", which seems to imply something similar to a garage door (or guillotine if the proper safeties are not installed). – Tester101 Mar 29 '16 at 12:48

You're right. In either case, you're also correct that designing the system is beyond the scope of this site. – Tester101 Mar 29 '16 at 12:58

To do so, you'll need a new motor & not a new switch. The new motor needs to be much like a Garage Door Opener's motor with similar circuitry, by having its own built-in & adjustable limiter switch. Then, you'll be able to press the switch once & walk away, for raising & lowering.
