This is all I have been able to find and behind the switch is the large panel on the left and reverse of that is a printed circuit board.I mean what is behind the push button that actually operates the circuit
As it resets every time you stop the vehicle it must only be a momentary contact switch not a latching mechanism.
Typically momentary contact switches are designed and built with a very low duty cycle capability.
For example they will only be carrying a current for a moment and not continuously, so duty cycle may only be 5% or maybe as high as 50%.
This means they are only designed to be on 5% of the time and off 95% of the time or 50/50.
Rarely ever are they designed to be switching 100% of the time.
I recall someone posted a year or more ago pictures of what was behind the panel but I can't find it.
I have circled the switch mech in red and the indicator light in yellow.
I am not that knowledgeable on automotive printed circuit board switches so someone here may be able to identify this type and it's operation.
pretty sure that if it burns out or breaks you will probably need to replace the entire circuit board, which at Ineos rates is probably the wrong side of $1,000
