I'm surprised it is called a switch rather than a push button but that's what Honda calls it.
This switch is an OEM part which I trust will work as designed for some time though the original should have worked much longer than 5 years. 2015 Fit. I don't know if the new part number is an upgraded design but that is what I ordered and received, a J02 while the original part number ends with J01. I felt the extra money spent is insurance. It costs more than an after market start stop switch but was priced much better than at several Honda dealers in my area. The part fixed my intermittent start problems and warning light problem.
