Can anyone tell me if there is a modification that can be done to the K2579 timer module so that it will still function with a latching trigger contact instead of the standard non latching push button pulse trigger contact?
Perhaps you can couple the latching trigger contact(s) to the 555 vis a capacitor. The 555 will react then on the high–> low transitions of the contact inputs.
