I have a sonoff switch with 4 outputs

What is the output from the switch that would go to the pulse circuit?

 

What is the output from the switch that would go to the pulse circuit?

The push button on the sonoff switch shorts ground wire to sense circuit. Would like to replace the push button switch with a normal toggle switch.

 

I think this should do the job :


Edit: Inputs of the three unused gates in the IC should be grounded.

Unfortunately that circuit will have glitches at the output due to the mechanical switch bounce.
Below is a circuit using CD4093 Schmitt trigger NAND gates to generate the XOR function with added debounce function.
Note that the output doesn't respond to the simulated input bounce (yellow trace) at the start.

Good catch. Thanks. Also, I showed the switch as momentary when I intended non-momentary .
