limitswitches

This video looks at how to connect limit switches to motors to control their mechanical stopping points.

Excellent Video, explanation using simple terms

Hello your Video war's very very helpful ! You made my day !

[@williamwachter3279]

Nice! Clear diagrams with a clear explanation in a Scottish brogue.

[@mountainsprings3303]

Excellent, and well illustrated.

[@Reeseshead]

thanks

[@vikashbihar4766]

Great explanation

[@randycarter2001]

You can eliminate the diodes by wiring the limit switches in place of the cross connection on the reversing switch. Just relocate the red motor wire to the terminal closest to negative power label in the drawing.

Genial!

Thanks for an easy-to-understand diagram and video. What size diode are you using?

[@AztecWarrior69]

That depends what size you need.

Hi, can I had a question regarding to the Diagram based on this video which is “Diodes” from the right if this connected to the positive of DC Motor?

I have two whisker limit switches that are controlling a warning light. When a door opens, the light goes on. When the door hits the second whisker limit switch, light goes off. It works, but I hear a "clicking" sound from the AC/DC power supply when the second limit switch put the light in the "Off" mode. Any idea if this is normal? Thank You

[@tedbastwock3810]

What would happen if we reversed the diodes so the cathodes rather than the anodes face one another?

[@firestick1121]

What rate are the diodes Dave

[@byLokie]

Great...So I am building my Granddaughter a 3 storey dolls house from scratch with a Elevator from Ground to first floor.
But instead of the "2possition,Double throw" I wish to put a push button on G and on1st to call the lift up or down. Just like we do in real life.
Could you help or point me towards a diagram for independant buttons? Thankz

[@mateusbarros8090]

Where can I find this kind of motor structure?

[@gtechnosinc2518]

And what kind of diodes?number?any information on that?

You don't need the diodes. You split the positive, between the power supply and the switch, wire your switches there, and wire the positive to the each pin of a cross connect, and then just wire the negative the regular way. You remove having to use Diodes.

Can you do a quick diagram for this?? Would be really helpful!

Before the comment where I say "Uploaded", I tried informed you that was going to upload and to check to see when I do. That was about 15min after your comment/request.

you see it? @@psychobillytetch

How can I pause/stop the switch inbetween

[@AztecWarrior69]

By using a DPDT switch with Center OFF. On - Off - ON. Shown at 4:02, you can see the Center Off, but I don't think he ever mentions it tho. Since the one he is actually using is a On - ON. You can see that there is no Center Off. 10:55. You can use a Momentary DPDT, so that you press it one way and let go, it returns to Center off.
