JOHNSON Vacuum Switch

- For automatic shut off operation
- To prevent pump damage
- The vacuum switch works with all selfpriming impeller pumps and should be used for e.g. bilge pumping/emptying of tanks to prevent the pump from running dry.
- The vacuum switch automatically shuts the pump off when the bilge/tank is dry. With the switch fitted, you can start the pump by remote push button or manually by depressing lever on the switch.
