When the liquid is aggressive enough to attack polypropylene or acetal, PVDF Kynar is the answer. The 10-782-KR uses the same ERECTA SWITCH foundation switching element — same hermetically sealed reed switch, same field-reversible float, same 1/8″ NPT jam nut mount — but constructed from PVDF Kynar for compatibility with concentrated acids, caustics, oxidizers, halogens, and high-purity process fluids. The material of choice for semiconductor wet processing, chemical dosing, and any application where the liquid chemistry rules out every other plastic.

A float level switch like the 10-782-KR is a point-level device: a float rides the liquid and actuates a magnetic reed switch at a set height, giving a simple on/off signal — no power, no firmware, no calibration. "Sensors" usually means continuous measurement (ultrasonic, radar, capacitive). ERECTA SWITCH targets reliable discrete-point control.
The 10-782-KR is used for pump start/stop control, high-level overflow protection, low-level dry-run protection, and tank or reservoir level alarms in OEM equipment. The modular ERECTA SWITCH system is built into laundry, HVAC, water-treatment, hydraulic, and chemical-handling machinery.
Choose the material to match the media: Polypropylene (PP) for general aqueous, acids, and bases; Acetal (AC/Delrin) for solvents, fuels, and hydrocarbons; Kynar PVDF (KR) for aggressive or harsh chemicals. Every ERECTA SWITCH model is offered in all three materials.
The 10-782-KR is point-level — it provides a discrete on/off signal at a set height. For multiple switch points, use a multi-level extended-stem set (2-, 3-, or 4-level) instead of a single continuous sensor.
ERECTA SWITCH offers vertical top-mount, bulkhead, and extended-stem configurations, plus side-mounted single-point models. The mount style is part of the model number — select the configuration that matches your tank geometry.
Point detection is repeatable and mechanical. The trip height on the 10-782-KR is set by the 10-715 Precision Nipple, ordered separately in 1-inch increments (1″–70″), so you place the switch point exactly where the application needs it.
