German to English Tech/Engineering construction, Sensorik

This is an item on a list in a Swiss residential building specification.

From the context, I guess it's a floor switch for opening and/or closing an automatic garage door. I imagine it's the same (piezoelectric?) technology sometimes used at road intersections to trigger the traffic light change sequence.

Personally, I'm only familiar with photoelectric cell detection systems for this application, but the prefix "Boden-" tends to rule that out. I guess it's just another case of the Swiss doing things a little differently.

Assuming I'm on the right track, what I need is the English term for this system. (Floor switch? Floor sensor? Floor sensor mat?)

Assuming I'm on a Holzweg, please set me straight.
