The 20-614 series provides top-mounted, low profile receptacle switch sets for liquid level sensing applications. The rain-tight receptacle accommodates AWG 20 gauge stranded wire, features a self-sealing cap screw, and includes a 1/4 NPT conduit nipple that rotates 360° for positioning flexibility. Available in Wet Open (WO) and Dry Open (DO) configurations, with three material options to match your chemical environment. Rated at 20 PSI @ 60°C. RoHS compliant.
General-purpose material with broad chemical compatibility. Recommended for water, mild acids, and most aqueous solutions.
Superior dimensional stability. Recommended for hydrocarbons, solvents, and weak acids where polypropylene is insufficient.
Maximum chemical resistance. Preferred for concentrated acids, chlorinated solvents, aggressive chemicals, and high-purity applications.
A float level switch like the Series 20 level switch 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 Series 20 level switch 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 Series 20 level switch 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 Series 20 level switch 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.
