    Illuminating Switch with 2 LEDS (as switched-blue, not switched-yellow)

    Hi, I hove some illumineted switches (blue, which is allway on). Want to modify it this way: Add another LED, yellow one which will be on as long as the switch being switched. Only one LED will light on at the time. Blue on (not switched) and yellow off. Yellow on (switched) and blue...

    4-position switch through 1 wire - decode - to 4 wires

    I tried yesterday following setup: - R1=8K2, R2=2K, R3=2K (range 1,97V - 3,93V) (input1 - 2) - R1=1K6, R2=2K, R3=2K4 (range 8,34V - 10,37V) (input3 - 4) Output voltage of the switch: 1. position - 0,14V 2. position - 2,91V 3. position - 6,23V 4. position - 9,39V Not Switched - 12V...

    4-position switch through 1 wire - decode - to 4 wires

    I knew it can be somehow calculated... made and formula V1 and V2 is known you set just R2 Voltage between R1 and R2 = V1 and voltage between R2 and R3 = V2 R1 = (R2+R3)*(V/V1-1) R3 = R2*( (V/V1) / (V/V2-V/V1) ) took me some minutes, but made it :) i mean the formula...

    4-position switch through 1 wire - decode - to 4 wires

    Hi there... Thanks a lot Blueteeth!!! Still dont know how to calculate R1, R2, R3 resistors for voltage dividers. If it would be 2 resistor on single rail, i would knew, but three.... dont know. And didnt found any calculator, or formula. V reference 1 = ? V reference 2 = ? Or to create 2...

    4-position switch through 1 wire - decode - to 4 wires

    Thanks a lot, and i hope last question: Do I ignore the RV, and instead of it the input would be mine Switch's output to IC1A negative and IC1B positive ??? the range is really set by R1/R2 and R2/R3 means what??? for example for the range app. from 480Ω to 600Ω, the R1, R2, R3 would...

    4-position switch through 1 wire - decode - to 4 wires

    Thanks a lot.... - I need the output voltage the same as input = +12V So which one do you consider most suitable for my needs? does the windows comparator output voltage is the same as input? I need two comparators for each output, right? So I need 2 quad camp, for example LM239???

    4-position switch through 1 wire - decode - to 4 wires

    or something like this each for each output?

    4-position switch through 1 wire - decode - to 4 wires

    Hi there, thanks to both of you for replies. Diagram would be much better. (I want just one output to be active at time, coresponds with the selected input)

    4-position switch through 1 wire - decode - to 4 wires

    I will rather modify the picture, cause, there is no MCU. Just 4-position switch with added resistors to each position, and the output of the witch is single wire. And I need a device with four outputs which will recognise, which position was switched. I dont want it done with MCU, cause I...

    4-position switch through 1 wire - decode - to 4 wires

    Hi there, need help with decoding 1-wire output from switch (each position another resistance) Thanks a lot

    IN<250ms = 50msOUT // IN>250ms = 50msOUT + T + 50msOUT

    Thanks for response It is an ordinary switch, so when pressed it gives +12V pulse till being released. And when it is pressed for longer than 250ms i want to make it another short output impulse. (otherwise it will give only one pulse at start, at being pressed) When pressed input voltage is...

    IN<250ms = 50msOUT // IN>250ms = 50msOUT + T + 50msOUT

    Hi there. Input impuls is from microswitch 12V source Output implus should be around 50ms or more. In case of the input impulse will be shorter than 250ms - output impuls 50ms should be once right after pressing the microswitch. In case of the input impulse will be longer than 250ms -...

    Analog LED (touch) switch - without uP

    to 4poyros: you are right... I am looking for panel (touch) switch. Something like "Capacitance touch switch", but done by 2 LEDs. One which will be still on, and the second one used as sensor. The sensor will sense the light reflected from finger, which will be close enough (pressed switch)...

    Analog LED (touch) switch - without uP

    Hi, I saw many switches that are using uP and code. 1) Is there a way how to make it analog way? I dont care if there will be 2 led if needed... One as Light source and second as recipient (sensor). 2) It should have two ouputs based on time of being "pressed". - when i "press"...
