THE ULTIMATE SWITCH
The Ultimate switch family is the most reliable switch on the market. Tested to over 250,000
cycles, they have proven their reliability. Each switch comes with a 5 year warranty. The
Ultimate Junior and Ultimate Mini feature a non-magnetic sensor tube to actuate a pump
or alarm. The Ultimate Senior has two switch sensors which allows the operation of a pump
and alarm. Each switch comes with a stainless mounting clamp.
JABSCO / GROCO / RULE “AIR PRESSURE” SWITCHES
These remotely mounted switches are ideal for actuating self-priming or submersible pumps
where there is insufficient room in the bilge for a float switch. Both switches include an air
bell, tube (3' with Groco, 10' with Jabsco), and the switch (Jabsco switch is sealed within a
molded enclosure). Their principle of operation is based on the air pressure that develops
when water rises up the tube from the air bell. The compressed air actuates the switch by
pressing up against the enclosed diaphragm.

BALL BEARING, MERCURY AND ELECTRIC SWITCHES
The Sure Bail utilizes a mercury float enclosed under a protective cover that incorporates
a manual test feature. The Johnson 26014 uses a ball bearing that actuates a micro switch
within the float as the water level rises. The Ultima Switch™ by Johnson uses “field effect”
technology to sense rising water. No moving parts means long life and no battery drain from
stuck switches. This switch is unaffected by oil, fuels and debris.
