Equip your bilge pump with an automatic float switch for peace-of-mind and worry-free operation of your pump. A switch will automatically activate the bilge pump when the water level rises in the bilge and deactivate the pump as the water level is lowered. The Fully Electronic and Automatic Ultima Switch, Electr-Magnetic Float Switch and a traditional Float Switch; all Mercury-free.

Ultima Switch - Electronic Automatic Switch

The electronic automatic switch, Ultima Switch uses the patented Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are totally sealed and are never in contact with the water, will not corrode and are not affected by oil or foreign debris.

No moving parts, totally sealed solid state electronics and field detectors, no mercury and no exposed sensors eliminate corrosion possibilities and make the Ultima Switch environmentally sensitive.

Ultima Switch activates at a 2" / 50 mm fluid level and deactivates at a ¾" / 20 mm fluid level. A three second delay prevents false starts.

Ultima Switch is rated to handle pumps up to 20A at 12 V or 24 V.

Electro-Magnetic Float Switch

Electro-magnetic float switch offers a combination of reliable solid state electronics and a sealed float switch. False start prevention, no mercury, high impact plastic and encapsulated electronics adds up to dependability.

Activates pump at 2" / 50 mm water level, deactivates pump at ¾" / 20 mm water level.

The switch is designed to attach to the Johnson Pump Cartridge bilge pumps. When attaching to other Johnson Pump bilge pumps, use the adapter provided.

AS888 - Automatic Float Switch

The AS888 automatic float switch has a time-proven micro switch without mercury. When water exceeds the acceptable level, the pump is turned on by a rolling steel ball, which changes the pressure on the micro switch. For fully automatic bilge pumping operation, connect the automatic switch to your bilge pump. The AS888 attaches to any Johnson Pump bilge pump through a clip on “T-slot” and can be used with 12, 24 or 32 V systems.

The complete switch panel gives you full control of your equipment. Simply depress the rocker switch for manual or automatic bilge pumping. The automatic feature operates in combination with the installed automatic bilge pump float switches, or electronic sensing of the AUTO pumps. The three-position switch panel has an integrated 1/4"x1-1/4" fuse holder, 3-position ON/OFF/MOM rocker switch with indicator light, all framed in an aluminium mounting plate. Note! Fuses are not included.

Bilge Alert - High Water Alarm with Ultima Switch

High water alarm with Ultima Switch featuring digital technology using the patented Mirus field effect. Totally sealed fluid detector is never in contact with water, will not corrode and is not affected by oil or debris. Bilge Alert detects water and sends a signal (3-second delay) to the alarm and switch conveniently mounted on a panel. Three way rocker switch allows alarm to be tested, turned off and armed (Test-Off-Armed).

Bilge Alert - High Water Alarm with Sensor

The Bilge Alert high water detection alarm utilizes field effect technology to detect the presence of liquid. The detector is highly reliable, durable and takes advantage of advanced sensor technology. The detector activates an alarm of 100 db after a delay of 8 seconds from being exposed to water.
