The switches in the Yamaha pedals are of good quality and unless you received a faulty part, would be unlikely to wear out with normal use

These days, most keyboards have the option to switch polarity internally either thru a global bemusement or by sensing whether the pedal is engaged at startup and adjusting accordingly (never press the sustain pedal while turning your keyboard on, you may very well cause an issue you don't expect and are confused by - turning on and off again without the pedal depressed will clear everything up in those cases.)So - build quality, excellent.

Quality seems good

It has a firm feel to it--good quality.

Good solid quality.

The sustain pedal is high quality and functions well with my Yamaha DGX230 keyboard

Great weight and quality to it as well.

Heavy duty construction, non-slip base (for those smooth stages) and typical Yamaha quality make this the best all around foot pedal for sustain--and much, much more--out there.
