    Forumers can I ask you for help in connecting the wiper motor system to the left-right switch (photo in the attachment) and two limit switches.
    I also attached a picture with the layout elements that I would like to combine.

    Thank you in advance.

    Describe how it should work.
    And try to connect if something goes wrong it will improve.

    The motor will be connected to the screw moving the nut. Limit switches are to stop the nut at the left and right end of the screw. And the left-right switch will control the engine.

    Would such a thing pass the exam?

    Maybe at the beginning, draw it yourself without the limits, and then include them. It will be easier for you to understand how it works.

    This is the same (in electrical terms) switch as from one post. They differ in casings. In addition to NO (normally open) and NC (normally closed) contacts, limit switches are also provided. You haven't used the latter in your diagram, think about why, what role it plays and what would happen if you connected in the way you drew. In which direction the engine will spin, which will happen when a nut reaches one of the ends. As a hint, analyze how the limit switches work, maybe you have some, e.g. removed from the printer and the meter, you can measure what happens in such a situation. Instead of giving the P / L switch, the PS may be enough for you with the switch and limit switches, then the motor, after receiving the voltage, would rotate to the left and then turn back. The direction of rotation would be constant, regardless of the starting position.

    Analyze the limit switches.

    Diagram of colleague REMUR. work :) . With a small 'but' the wiper motor draws a little more than 1A. So use a suitable diode. Limit switches also for the appropriate current.

    @ Art.B
    The engine has, for example, outside the window, how many wires do you need to control from the room?

    The operator must be able to choose whether the engine will turn left or right. The system will not work often and long. The whole will be mounted in one room on one machine. Will the Art.B solution "without diodes and oddities work or do I have to have something else? Alternatively, how strong diodes should I use?"

    Thank you very much for your help.

    Added after 2 [hours] 39 [minutes]:

    Can I power it from a 19v 3.5 A laptop charger? Will it be enough? I know the voltage is too high, but the engine will run a maximum of a minute.

Topic summary

The discussion revolves around connecting a wiper motor system to a left-right switch and two limit switches. Users suggest starting with a basic diagram without limit switches for clarity, then incorporating them to understand their function in stopping the motor at both ends of the screw. The importance of using relays to handle the motor's current is emphasized, with recommendations for automotive relays and appropriate fuses. The author seeks confirmation on the schematic and inquires about powering the system with a 19V laptop charger, to which the consensus is to use a 12V power supply instead.
