Connecting a Stair Switch as a Single-Pole: Phase to Red Socket Issues

raf2 25338 19
Best answers

How can I wire a stair switch as a single-pole switch so the lamp is not permanently live?

Use a normal single-pole ON/OFF switch instead; a stair/cross switch is the wrong device for the simple two-wire circuit you describe [#14518708] The two conductors you call "0" are not neutral and phase; they are phase wires, with one permanently live and the other only disconnected by a breaker, so there is no neutral at that point [#14520697] If you still want to verify the switch, use an ohmmeter to find which terminals connect to the red common when the switch is toggled [#14522166] If the lamp still stays live, the wiring in the box is probably different from what you think, so a photo of the connected breaker and wires is needed [#14518703]

    Hello!
    I would like to connect the stair switch as a single-pole switch, but when I connect the phase to the red socket and the 0 to the pole, I still have current in the bulb all the time, regardless of the switching of the switch. How else to connect it?

    You probably have other connections. Red plus any on the other side.

    Hello.
    Your description shows that you have a cross stair switch, which should be replaced with an ordinary ON/OFF bistable switch.

    I would like to connect the stair switch as a unipolar one, but when I connect the phase to the red socket and the 0 to the pole, I still have electricity in the bulb all the time, regardless of switching the switch. How else to connect it.


    What do you think is "0" and a pole. Be glad there is no short circuit.
    It would be more useful if you took a photo of the existing circuit breaker with the wires connected.

    Well, when I connect an ordinary single-pole switch, everything is ok. The diagram of this switch is shown in the picture. I'm not afraid of a short circuit, the differential will always work

    Take a picture of this circuit breaker with the wires connected!

    Attached is my connection diagram. of course, I connect the 2 poles alternately

    What does "I connect O" mean here?

    And don't you sometimes connect "0" (whatever it means) to two terminals at the same time?

    I mean "-" I have 2 wires coming out of the socket, one live and the other not

    There's no downside there. This is a phase wire, only disconnected by a circuit breaker.

    By shorting both wires together (without the switch) do you get the effect you've been fighting for from the beginning?
    Otherwise, me

    and I will have to go back to my elementary school education.

    Yes, without a switch, a short circuit of 2 cables results in the lamp being lit, and when I connect this stair switch, I cannot get this effect

    Check with an ohmmeter which switch terminals open and close relative to red when switching.

    Everything works fine on the ohmmeter

    So when you turn off the switch, the resistance increases to infinity, and when you turn it on it decreases to zero?

    Then everything works fine except your head.
    Your continued actions could lead to personal injury or ultimately to the death of others.

    PS I have one more question. Have you taken the SEP exam entitling you to modernize electrical installations?

    Do you have well stripped wires and are you plugging them into the switch correctly?
    You may need to press the lock to push the wire deeper into the terminal.

    My suggestion to the author. If you can't handle changing the purpose of the stair switch, buy a single one.

    I'm closing the topic.

Topic summary

✨ The discussion revolves around connecting a stair switch as a single-pole switch, where the user experiences continuous current in the bulb regardless of the switch position. Responses suggest that the user may be using a cross stair switch instead of a standard ON/OFF bistable switch. Clarifications about wiring, including the meaning of "0" and proper connections, are provided. The user confirms that an ordinary single-pole switch works correctly, and troubleshooting steps include checking wire connections and using an ohmmeter to verify switch functionality. Ultimately, a recommendation is made to purchase a single-pole switch if the stair switch cannot be adapted.
