The Jabsco 4732-000 (J41-011) vacuum switch prevents dry running damage to electric clutch pumps and is suitable for 12 and 24 volt electric clutch pumps up to 15 amp. The vacuum switch automatically shuts off the power to the pump when the bilges are clear of water, saving the impeller from dry running damage. It does so by sensing loss of inlet vacuum when the bilge is dry and air enters the pump.
