Select the size that best matches your tank or reservoir dimensions and installation requirements.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this float switch be installed at the top or bottom of a tank?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The vertical mounting design allows installation at either the top or the base of your tank. Mount it at the top to detect liquid rising to a set level, or at the bottom to detect when the liquid falls below a minimum threshold.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this float switch suitable for outdoor or extreme-temperature environments?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The stainless steel construction resists corrosion, and the switch operates across a wide temperature range of -30°C to +125°C, making it well-suited for both indoor and outdoor applications, including harsh industrial or chemical environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this water level sensor require any external power source or battery?\u003c\/h4\u003e\n\u003cp\u003eA: No battery is required. The float switch operates on a simple mechanical principle — as the liquid level changes, the float rises or falls, opening or closing the circuit. This straightforward design requires no complex electronics or dedicated power supply.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What sizes does this stainless steel float switch come in?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This float switch is available in four sizes: 65 mm, 100 mm, 150 mm, and 200 mm.
