Replacing Tactile w Hat Switch

[LtFransky]

I'm currently working on a joystick-bash project where I'm taking a handle and integrating it onto a different base (and electronics) while maintaining the programming capabilities of the new base. The new base uses 4 tactile switches for a POV hat and several of them are DOA. If I replace them with a Hat Switch by soldering the approprate leads to the circuit board, will it mean the same thing to the programming software?

HAT switch consist four micro switch tactile placed around a axis pin that press one (N,S,W,E) or two (NW, SW, NE, SE) switch.

 

Probable this HAT have five wires, one common, wire your new four tactile switch's in accord.

 

In true you can wire eight new switchs in one HAT position whit diodes, to use NW, SW, NE, SE positions. But in this case note that you don't use N and NE... switch's at same time.

Be careful if you pulled the hat off an older game port joystick. The old hats used resistance to determine direction and not individual switches. If the hat your trying to use has 5 leads on it then you should be able to wire it up to the existing 4 tactile switches.

 

If the hat your trying to use has two leads you may be able to doctor it up to work. I had to de-solder resistors and cut traces to separate the tactile switches in an old hat to hook it up to new electronics. Essentially these old hats are the same 4 tactile switches just prewired to set of resistors so you could read them like an axis.

I had some old hat switches out of a TM FLCS/TQS that I was going to use.

 

Actually Sokol, I'd be interested in seeing how that diode wiring is done.

EDIT - I realize that your case is use old HATS into new (USB?) circuit.

 

FLCS/TQS HAT's use 5 wires, one common.

 

Is good check whit multimeter for interconnected switch's - I have headache with CH HAT in gameport CH Combatstick converted to USB with BU0836.

One HAT have a occult trial embedded in PCB:

 

In drawing "Cortes" mean "Cuts" and "Trilha oculta no verniz" mean "Trial hidden under varnish"

 

In this case S and W switch's were interlinked by hidden trial.

 

If you only desire wire old HAT's into new USB controller, just consider each HAT as four individual switch's.

 

You don't need DIODES unless the new USB controller request (diode matrix).

You are allow to use only N, E, S, W positions of HAT.

To use NE, SE, NW, SW you need wire these HAT into HAT position of USB circuit.

 

To circuit don't make difference if you use HAT or four individual switch's.

You can program in the same way.

 

HAT are only four individual switch's in a common base.

Ah. I think I understand.

 

The TM hat can just wire straight in. The switches have the 5 wires with the bare wire connecting 4 posts (I think to prevent phantom signals).

 

The existing circuit is out of a Saitek X52. I'm just changing the handle to an F-18. The only issue is adapting the hats to the electronics. But it doesn't seem to be a big deal.
