My unit never shipped with a button.
It was recommeded to me that I could use any similar button to do this. At minimum it can be a SPST, but I found that most switches are DPDT. The momentary contact needs to be between the signal (white) and ground (black). The positive (red) does not need to be connected, but is useful if you want the button to be lit.
The connector pictured here is a 3 pin servo lead, however, more recent versions of Openevse seems to use a different type of 3 pin connector (looks like JST type). I shaved off the edges of the servo lead so it fit into the connector.
what type switch is it? momentary contact or push on push off? spst or dpst? etc.
Pish button is to enter configuration menu, set timers, add xxx kWh, charge for xxx minutes, etc.
What is the application of the push button? To turn the EVSE off completely and prevent a phantom power draw?
