SP6011e tact switch bypass

Questions
1

Hey All
Does anyone know what’s involved with bypassing the (On/Off) tact switch with a momentary switch? It appears its not as straight forward as just connecting switch cables from pin 1 to 4 or 2 to 3. It looks like the tact switches are the same between the SP611e and the SP511e. Does it require a resistor or something?

Those switches are just momentary push buttons.
They are connected to the necessary resistors on the board, so if you solder wires directly to the correct pins off the button(s) it will work.

The trick may be finding the correct pins.
You’ll need a meter to test, but I seem to recall they aren’t the “obvious” pairs of pins.
Something like 1-3 and/or 2-4 (using your numbering scheme).
You also need to verify that both sides are connected - the switch is SPST.
If they’re not connected (switch is DPST) then one set of pins may do nothing.

Bypassing the tact switch with a momentary switch can be done, but you’ll need to ensure that you’re maintaining the proper functionality. Here’s how you can approach it:

  1. Identify Pins: Confirm the pinout of the tact switch. Typically, you’ll have two pairs of pins that connect when the switch is pressed.

  2. Wiring: Connect the momentary switch in parallel with the tact switch:

    • Connect one side of the momentary switch to one pin of the tact switch (e.g., pin 1).
    • Connect the other side of the momentary switch to the corresponding pin (e.g., pin 2).
    • This allows the momentary switch to simulate the same action as the tact switch.

  3. Debouncing: Depending on the circuit, you might need to add a resistor (usually 10kΩ) in parallel with the momentary switch to help with debouncing, although many circuits handle this in software.

  4. Testing: Once wired, test the setup to ensure that pressing the momentary switch activates the same function as the original tact switch. https://www.pneda.com/

  5. Configuration: Check any software settings, as some systems may need adjustments for different switch types.
