It has two switching points — one for a high-level trigger and one for a low-level trigger — allowing for automatic pump activation or shutoff based on water level changes.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this float switch compatible with swimming pools?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, the stainless steel double ball float switch is suitable for swimming pools and other aquatic systems. Its 304 stainless steel body resists corrosion from water exposure, and the wide voltage range (100–265VAC) ensures compatibility with most standard pool pump setups.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this float switch require any special installation tools?\u003c\/h4\u003e\n\u003cp\u003eA: No special tools are required beyond standard electrical wiring equipment. The switch connects via direct wiring (no battery needed). Always ensure power is off before installation and follow local electrical safety codes. The CE certification confirms this unit meets established safety standards.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a double ball float switch used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A double ball float switch is used to monitor and control liquid levels in tanks, pools, and reservoirs.
