Hi all sorry for the long winded green horn question. Any feedback would be greatly appreciated. I am building a custom gear shifter out of my old Logitech g27 steering wheel. It is all powered up and functioning correctly, but I am trying to use the zippy click microswitches from the left and right paddle shifters to work off of the three wires that run from the motherboard to the brake and clutch pedals which is are controlled by a potentiometer switches . I can not get this micro switch to function when hooked up correctly to the wires for the potentiometer. I can get it to function when I hook the three wires up incorrectly, but it cuts the power to the wheel/unit when I press the switch but does register in my controls of the game I am trying to configure this with. problem is it pauses the game when the power cuts out to the unit when micro switch is depressed. Is there a way to use these zippy click style micro switches donated from the paddle shifters to make function off of the three wires for the potentiometer switches(brake and clutch pedal) ? I believe it is a zippy brand sm1 click style microswitches and the potentiometer p/n is 103870-1000 Thank you for your help in advance

 

A schematic Diagram and Pictures are required.

Here’s a picture of the dissected g27 steering wheel. It is functioning and factory controls are communicating with my computer properly. Second picture is of the two click style microswitches I am trying to make operational by using the power leads for the potentiometer switch for the brake pedal activation which I have attached in the third picture. The only time I can make these microswitches work, it causes the power to cut out on the unit while the microswitch is being activated and comes back on immediately once released?? Sorry I am green horn at this and I appreciate your efforts !

 

Of course this mess is just for testing purposes only and will be fixed and installed properly if I can get this to work

Here’s the Link to the zippy snap switch with specs

here’s the link to the info for a replacement potentiometer they recommend for the g27 brake pedal, I can’t find any other info on the potentiometer in my unit now, hopefully this link will give an idea of what potentiometer I am currently using. Mine does say 10k/70 1136 on the side if that helps.

 

Need a wiring diagram or schematic diagram of how you are connecting things.

 

Here’s a schematic. I am trying to use the power /communication from axis 2 and axis 3 potentiometer for my snap button microswitches. I have them wired 5v, white , ground to one switch and 5v, green, ground to the other switch

 

Where do the Switches enter into this Schematic ?

The switches will be mounted on a gear shifter if I can make them work.I unplugged the wires from axis two and axis three potentiometers and plugged them in to my microswitches. Green, 5v, ground to one snap button microswitch, white, 5v, ground to the second microswitch

 

Schematic please.

Schematics are the language of electronics, not words.

 

Fair enough, here is a marked up schematic.the Yellow markings are the snap button microswitches I am trying to install into the schematic as you will see. Please let me know if you require anything else. Thanks again for the help!

Stop and think about this. You use of the micro switches makes you controller think it has either a short circuit or open potentiometer when activated. Those pots are used to make the controller do what a car does in real life, turn a moving, variable input into a simulation electronically. When you substitute the switch for the pot it would be like slamming on the brakes or applying full throttle instantly in a car.

You will need another approach to make a paddle shifter, not the game controller your using now. A way will need to be made to make each push of the paddle to count up then back down as needed.

I think thats his intention, as in zippy

 

I suspect you are shorting out the 5 volt supply. UNTIL YOU DRAW A SCHEMATIC OF EXACTLY YOU HAVE THE SWITCHES CONNECTED we can only guess.

Les.

 

You could try NC to +5V, NO to gnd, and COM to the signal wire.
But the circuit may require some resistance to work.
So, add a series 10K resistor from the COM to the signal wire.
As requested, you need to draw a circuit of how you connected the switches. Your photos are not cleat enough.

 

Something like this would have been ok...

If the brake and clutch are operated, swap the wires to the NC and NO.

I thought his intention was to make a simulated paddle shifter? But I've been wrong before.
