When the pressure switch does work (after I tap it) there is an arc.. but the motor kicks on no issues.

My main concern is that the pressure switch is not cycling. I've had the emergency release valve go off more than once (that is a scary sound)so when I do run the compressor I monitor the run time and tank pressure closely.

The last two pressure switches were name brand (about $70 each) and lasted less than a year.

Is there any maintenance to the pressure switches? I haven't taken it off the receiver yet... I was hoping to be able to fix it without removing everything.
