Honda Insight seat ejection button

On the 2nd gen Honda Insight (2010-2014), to the left of the steering wheel, there is a bank of three switches. The far left switch is traction control on/off, a real button. The other two slots are filled with blanks. This thing is a fake button that replaces one of those blanks.

It consists of two pieces.
1. Black "blank" to fit the empty slot in the switch panel.
2. Yellow EJECT button, mounted on the blank by snapping in place with 4 small pips.

The button face is designed to be interchangeable, so you only need one blank per slot.
