Thread: Wiring a push buton switch

Take a picture of the back (Terminals) and front of the switch, so we know what your talking about.

Hi Chris,

if the switch is of European make, the two input terminals onto which you fasten the two leads of the mains cord, are marked "P". The other two are the output terminals for the motor (other countries often use similar markings, or numbers). These switch type are often two pole setups (with two identical and mirrored switches), so it doesn't matter to which "P" you connect either the live or neutral wire. For the machine itself, however, it may matter which of its two terminals is connected to live or neutral. In that case, you must determine first, which P is connected to which output terminal when the "ON"-button is pushed. The output terminal that is connected to live when on, is the terminal onto which you fasten the machine's live lead. The other one is for neutral.

I could make you a drawing but a picture of your particular switch terminal layout is the best way to give a definite answer.

Gerhard, ... what's going on?

6 lines???

We enjoy your answers and we expect them to be LONG!

Cheers,

Hi,

Thanks for the advice.

As suggested by Scott I have uploaded a photo of the switch. A front view in the machine and two views of the connections. There are no letters or any indication of how this switch should be wired up. Any suggestions most gratefully received

Thanks again

Chris

Pm sent.
I think if worked anyway let us know if u recive it

Hahaha, hi Paul !

yours is a reaction i will always treasure! Brilliant! The first endorsement in writing that my long yarns are not necessarily bad. Thank you very much indeed!

best of greetings from Holland!

Hi Chris,

the switch in your pics looks like the double pole switch that i expected to be there. The wiring seems to be straightforward as well. Blue and brown in, blue and brown out. My guess is that, when the green "on" button is pushed, one set of switch contacts connects brown with brown and the other set blue with blue. This is the regular setup for a double pole switch. The absence of any markings means, that specific "in" and "out" connections are not important for this particular switch. Important is, that both mains wires must be mounted side by side, so either at the switch's upper side (the upper half of the assembly, with the red button) or at the lower side (down half, with the green button). The motor leads are also mounted side by side, but at the opposite half of the switch assembly. Do not connect one mains wire at the bottom and the other one at the top, because the mains voltage may be shortcircuited when the contact is closed. I made some drawings to explain the right setup.

Before you carry out the above, make sure that the switch indeed has the layout that is expect. Do can do so by measuring it. If you are uncertain in any way, have an electrician carry out the replacement of the switch.

Thanks for all the really helpful comments. The jointer is purring away. All I need to do now is make some fine adjustments . Thanks again to everyone.
