Rather than relying on a mechanical rolling-ball switch, this float switch uses encapsulated electronics housed in high-impact plastic, so it activates the bilge pump once water reaches a 2 inch level and deactivates the pump when the water drops back to 3\/4 inch. A false start prevention feature keeps the switch from cycling on and off erratically as water sloshes in the bilge, which reduces wear on the pump motor and avoids nuisance cycling in rough conditions.\u003c\/p\u003e\u003cp\u003eBecause the switch is fully sealed and contains no mercury, it is a cleaner, safer option than older mercury-tilt style switches while still delivering long-lasting marine durability. The Johnson Pump 36152 is built as a direct replacement for older Mayfair Electro-Magnetic bilge pump float switches, making it a straightforward swap for boat owners upgrading or replacing a worn-out unit. It is rated for 12V systems with a maximum load of 15 amps, matching the electrical requirements of common small to mid-size bilge pump setups.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 36152\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Electro-Magnetic Float Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage:\u003c\/strong\u003e 15 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation Water Level:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeactivation Water Level:\u003c\/strong\u003e 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 3 inches long x 1-1\/2 inches wide x 3-1\/4 inches high\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-impact plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury Content:\u003c\/strong\u003e None (mercury-free)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Direct replacement for older Mayfair Electro-Magnetic bilge pump float switches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThe Johnson Pump 36152 is designed as a direct replacement for older Mayfair Electro-Magnetic bilge pump float switches, making it suitable for boats currently equipped with those earlier switch models.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Johnson Pump 36152 float switch do?\u003c\/strong\u003e The Johnson Pump 36152 is an electro-magnetic bilge pump float switch that automatically turns a bilge pump on and off based on water level, combining solid state electronics with a sealed float switch for dependable control.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAt what water level does this float switch turn the pump on and off?\u003c\/strong\u003e The Johnson Pump 36152 activates the bilge pump at a 2 inch water level and deactivates it once the water drops to 3\/4 inch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Johnson Pump 36152 contain mercury?\u003c\/strong\u003e No. This float switch contains no mercury and uses encapsulated solid state electronics and a sealed switch design instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage and amperage is the 36152 float switch rated for?\u003c\/strong\u003e The Johnson Pump 36152 is rated for 12V operation with a maximum load of 15 amps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Johnson Pump 36152 a replacement for an older Mayfair float switch?\u003c\/strong\u003e Yes.
