Replacement Air Switch/hose and electric pneumatic microswitch for your insinkerator or spa pump, button fits 32mm hole, other sizes available, no electric danger as switch is air operated E&OE

Bobs tip: before fitting air button to existing air hose, blow air with your mouth into hose making sure pump turns on and off, if not the hose may have water inside, the micro switch may not be working, check power supply, or the pump could be kaput. If the pump just hums, i.e. everything is OK bar the pump, it maybe jammed up or the capacitor is faulty or finally the motor windings are defective. Message me for answers.
