UltimaSwitch™
The UltimaSwitch is a highly reliable solid state switch which
uses no mechanical parts or toxic mercury to sense water level
and automatically controls a 12V DC or 24V DC bilge pump.
The switch activates the pump when the water level reaches 2”
or more and turns off the pump when the water level reaches
below ¾”. The Ultimaswitch automatically adjusts between 12
V DC bilge pump or a 24V DC pump without any adjustments
necessary.
Caution!
1. Connect an inline fuse of the appropriate amperage (specified
on the pump).
2. The UltimaSwitch is designed for 12 VDC and 24 VDC
operation only. Do not use any other voltages, do not use AC
or AC-DC converted power sources.
3. Failure to use the appropriate fuse and connecting wires
according to the instructions provided will void any SPX
Johnson Pump Warranty and may cause serious damage or
personal injury.
Installation
Location:
1. Mount the UltimaSwitch in a vertical position (Mount holes
towards the bottom of vessel) and close to the pump such
that the water level is equal on both pump and the
UltimaSwitch.
