    Hi all,

    Good to know this forum is exist.

    I have a project that I need a specific switch for it but I cant find it. I know the switch is exist but I guess I'm not searching it with the correct name.
    the switch I need suppose to be illuminated push button that can switch between 4 position - OFF, Low, Medium, High. (then again OFF, Low....)

    anyone have any idea ?
    thanks.

    By low, medium, high do you mean three different sources? Or is switch supposed to convert one source into three?

    You could perform the function using relays and a momentary switch. The one you describe is not a normal item and would be custom made. Very expensive.

    Typically that functionality is NOT build into the switch but whatever circuit the switch is attached to..

    Do you have more details? like whats it for? why do you need a replacement? what voltage/current levels?,etc...

    to be more specific, I need something that can work for me like a dimmer but in a fixed positions. the power source is 5v.
    if you have a better solution for me i'll be glad to hear, but it have to be with illuminated switch that have the 4 position function (OFF, Low, Medium, High).

    another thing, the switch / unit should be small as possible.

    Small, Iluminated, 4 position switch (3 pole) that changes the voltage on each pole. I don't see you finding anything like that already made.

    You could have a 4 positon 3 pole rotary switch but I've not see one iluminated then just have each pole supply your low, medium, and high values.

    You've not said if you wanted push button or rotary. You've also not said what values of low medium and high are.

    You just repeated the same stuff from your original post.. The ONLY detail you added was your power source is 5V.. MORE DETAILS..

    Is 5V high?
    What is medium?
    What is low?
    How much current?
    What needs this dimmer/What are you trying to power (datasheet/spec sheet?) ?

    Since I'm not an electrician you'll have to forgive me about the luck of information.
    I need the switch to be illuminated push button (not rotary) and it should work with 5v heating coil.
    the Low / Mid / High suppose to chance the temperature in the heating coil while the High is the Hottest point.

    Thanks!

    So this is for a e-smoke/dab vaporizer I'd guess..
    If so there are microprocessors in those "adjustable batteries" and a simple momentary switch is used and the micro monitors that and does whats needed to achieve the "adjustable voltage/wattage". (PWM I'm sure)

    As stated above a few times you will NOT find just a momentary push button switch that does that on its own.

    nope.. thats just a 4pdt on/off switch.
    A single switch with added no logic will ever meet your needs alone.
    There are many ways to do what you want.. but the answer is NOT just a switch alone. The most you can do with a push button switch alone is on and off or medium and low,etc...

    Not until you answer the previous questions about the power source/heating device specifications,etc... ;)
