    Default Wiring On/Off Toggle Switche

    Can someone please remind me how to wire a toggle switch to turn a single LED on and off using a terminal block in between the power supply and Light:

    Run one of the two wires through the toggle switch. The toggle switch is used mearly to interrupt (off position) or complete (on position) the circuit to the LED.

    Don't forget to include a resistor.

    That's weird , I posted the same thing less then an hour ago and my post is not showing . Yes , switch in between either of the 2 wires will work.

    Thanks guys so something like this perhaps:



    Moose, the lights I want to connect to toggle switches are those already on the wifes layout so yep, all resistors are already in place

    and Jan, yep I have noticed that as well - with my posts as well as others. I get the email notifications but when I click on the link in the email - the post isn't there ?

    An SPST Switch is the correct switch right? Or should I use another variety? Whatever is the easiest to wire.
    Cheers Tony

    Correct for the red wire. The black wire should NOT go thru the toggle switch.

    The way you have the black wire drawn, when you toggle the switch to break the circuit to the red wire, you will have the red & black wires connected that will short circuit...

    So keep the red wiring as shown but run the black from the terminal board straight to the light. Does that mean I could get away with using a 2 post toggle switch instead of a 3 post switch?

    Sorry for all the questions, it's been awhile since I've done this and to be honest, I am still confused by SPST, SPDT, DPST, DPTP switches and what they are all for

    And, no worries about the questions ... Moose had similar questions when building layout control panels a few years ago.

    Oh yeah, control panels - I gave them up for lent, or some other reason that I can't, or wont, recall due to this being a family orientated forum

    Now wait a doggone minute. You were uttering insults about Moose before this? Well Moose never, Moose mean NEVER, in all Moose's moose years has such a thing happened. To think Moose offered up advice, assistance, to, what turns out to be a low low low wombat. You, sir, are a disgrace to wombat kind! Good day, sir, Moose said good day!

    Okay so just so I am on the same train ... this is how I would wire a 2 post SPST switch:

    Yep, that'll do it!

    And, again, don't forget the resistor...

    Thanks mate and the lights already have resistors connected. I am assuming the resistor goes in between the switch and terminal board though.

    Ahh Moose ... only unkind thought I have ever had about a Moose were directed at them real ones in Anchorage. ALL other Mooses are good guys, especially the ones that can use hooves to use computers, type, build stuff and offer first class advice to lowly wombats

    Oooh, okay. Moose bad. The exact placement of resistor in curcuit is not an issue as long as it is in there somewhere...

    Nope, not bad at all Moose - better for you to point the resistors out than assume I"d do it ...

    Yes.

    And if it's a three-post switch (SPDT seems to be the proper term, although manufacturers confuse that...) make sure one of the wires (doesn't matter which one) goes to the center post, leave one of the outside posts (deciding whether the light will light up when you move the switch right or when you move it left) free.
