Tsurumi Float Switch 110 V Max 1 HP

Description

Automate submersible trash pumps and prevent dry-running motor burnout in wet sumps. The Tsurumi Float Switch 110 V Max 1 HP control unit manages high-load pump cycles. A wide-angle mechanical switch activates internal contacts as liquid rises. The 1.0-horsepower rating limits usage on massive commercial three-phase trash pumps.

Impact-resistant polypropylene forms the float housing, sealed against water intrusion with high-pressure polyurethane potting. Heavy-duty copper electrical contacts resist arcing erosion under 1.0-horsepower inductive motor loads. The flexible synthetic rubber power cable incorporates a piggyback bypass plug for simple testing. Stainless steel pipe clamps secure the tether bracket to pump discharge pipes. Chemical-resistant casing plastics resist sewage degradation.

Float Switch System Specifications

Basement contractors automate manual submersible dewatering pumps without complex control panels. The piggyback plug design allows instant conversion between automatic and manual operation.

• Inductive load switch manages single-phase electric motors up to 1.0-horsepower capacity
• Piggyback electrical plug connects straight to 110-volt wall outlets without hardwiring
• Wide-angle mechanical contacts trigger pump activation across adjustable tether heights
• High-impact polypropylene float shell resists chemical attack from raw sewage water
• Heavy 16-gauge power cable includes molded strain relief to stop water leaks
• Stainless steel mounting band clamps the tether collar straight onto discharge pipes
• Mercury-free mechanical switch contacts meet environmental and jobsite safety codes

Switch Electrical Bench Telemetry

Electrical bench testing confirms contacts handle 13.8 Amps inductive current across 115-volt lines for 100000 continuous test cycles. Contact resistance measures under 0.02 Ohms with zero contact chatter. Float shell seals endure 30 PSI external hydrostatic pressure without water intrusion. Switch operating angle triggers at 45 degrees above horizontal.

Worksite Performance Practical Notes

You clamp this float tether collar onto vertical discharge pipes using standard screwdrivers. Adjusting the free tether length sets the liquid activation level. Do not install this float switch touching pit walls. Rough concrete contact snags the float housing and causes pump dry-running failures.

• Inspect the float tether for entanglement around power cords every 30 days
• Clean grease films off the polypropylene float shell to ensure free buoyancy
• Test float movement by hand to confirm the internal mechanical switch clicks
