These kits provide the user with the opportunity to optimize their own multi-point switches and fabricate them in the field from the kit components. The standard ML5555 kits are furnished with two floats and a 2" pipe plug, with a maximum stem length of 43.19" (Includes 1 - 9" fitting and stem, 2 - 12" extension tubes, 2 - 4.5" switch capsules, 4 unions and an end cap). Users who require a 3rd or 4th level, can purchase adder kits to do so.
Assembly of Madison's Multi-Point Switch Kits generally involves the following steps: Lay out the supplied components in the configuration that your application requires. Determine the lengths of the Connecting Tubes and cut them accordingly; de-burr and smooth the sharp edges of the cut tubes prior to installation. Perform a trial assembly and, using a continuity indicator (light, buzzer, Ohm Meter, etc.), verify that the switch actuation levels (L1 and L2) are at the required levels and the switch action (Normally Open or Normally Closed) is correct for your application. When switch set-up is satisfactory, tighten the fittings and apply thread sealant to the pipe threads on the top fitting before installing the switch into your tank.

Switches are rated for resistive loads. See our Electrical Considerations for UL guidelines for current (Amperes resistive) at different voltages.
