Johnson Pump 26014 AS888 Automatic Bilge Pump Float Switch, 6-32V, 15 Amp Max

The Johnson Pump 26014 (AS888) Automatic Bilge Pump Float Switch is a mechanical float switch built to turn a bilge pump on and off automatically as water rises and falls in the bilge. Instead of relying on mercury or delicate electronics, it uses a rolling steel ball that shifts inside the housing as the float tilts, changing pressure on a sealed ceramic micro-switch to trigger the pump. An anti-spike feature keeps the switch from rapid-cycling on and off, and it gives an audible click when it engages before water reaches an unacceptable level.

The housing is ultrasonically sealed thermo-plastic, which keeps water out of the switch mechanism for reliable long-term use in a wet bilge environment. It attaches to any Mayfair or Johnson Pump bilge pump through a clip-on T-slot mount, making it a straightforward add-on for pumps that do not already include automatic operation. The switch is rated for use across 6V, 12V, 24V, or 32V systems, giving it broad compatibility with common marine electrical setups, and it carries a maximum amperage rating of 15 amps. It is built as a direct replacement for older Mayfair float switch models, so boat owners upgrading or replacing a worn-out switch can install it without changing the rest of the bilge pump setup.

Frequently Asked Questions

What does the Johnson Pump 26014 float switch do? The Johnson Pump 26014 automatically turns a bilge pump on when water rises and off when it drops, using a rolling steel ball that shifts pressure on a sealed micro-switch rather than mercury or open electronics.

Is the Johnson Pump 26014 compatible with my existing bilge pump? It attaches to any Mayfair or Johnson Pump bilge pump through a clip-on T-slot mount, and it is built as a direct replacement for older Mayfair float switch models.

What voltage systems can this float switch handle? The Johnson Pump 26014 can be used on 6V, 12V, 24V, or 32V systems, with a maximum amperage rating of 15 amps.

How does the anti-spike feature work on this switch? The anti-spike feature in the Johnson Pump 26014 prevents rapid on-off cycling of the bilge pump, and the switch gives an audible click when it engages before water reaches an unacceptable level.

What are the dimensions of the Johnson Pump 26014 float switch? This float switch measures 3 inches long by 1-1/2 inches wide by 3-1/4 inches high.

How much does the Johnson Pump 26014 float switch weigh? The Johnson Pump 26014 float switch weighs 0.5 pounds.

What is the housing made of? The Johnson Pump 26014 has an ultrasonically sealed thermo-plastic housing that protects the internal switch mechanism from bilge water.

Does this float switch use mercury? No. The Johnson Pump 26014 uses a rolling steel ball and a sealed ceramic micro-switch instead of mercury to detect water level.

How is the Johnson Pump 26014 mounted? It mounts via a clip-on T-slot design that attaches to any Mayfair or Johnson Pump bilge pump, without requiring separate hardware.

Will the Johnson Pump 26014 replace an older Mayfair float switch? Yes, the Johnson Pump 26014 is a direct replacement for older Mayfair float switch models.

What triggers the pump to turn on with this switch? As the float rises with water level, a rolling steel ball inside the Johnson Pump 26014 changes pressure on the micro-switch, closing the circuit and switching the pump on.
