Product Description

The 10-785-PP is a side-mounted liquid level switch that solves the problem of tanks with no top access. A unicellular split-float clamps around the horizontally oriented 10-782-PP stem and travels in a vertical slot as liquid rises and falls, converting Compac's standard vertical-operation switch into a side-mount configuration without custom fabrication. Polypropylene construction handles water, mild acids, caustics, detergents, and most aqueous solutions up to 180°F (82°C) at 100 PSI (6.9 bar). As part of the ERECTA SWITCH modular system, every component is field-replaceable without pulling the tank or cutting wires.

Key Features

Engineered specifications and field-service advantages — not marketing language.

1/8" NPT side-wall mount

Fits the smallest standard bung on tanks where top access is blocked by roof structures, process equipment, or stacked vessels.

Unicellular split-float configuration

Two-piece float clamps the stem without disassembly — orient magnet-up for open-on-rise, magnet-down for close-on-rise. One SKU, two electrical configurations.

Sealed 10-782-PP reed switch

Hermetically sealed reed contacts rated 20 VA, 0.5A @ 120 VAC, 1.0A @ 24 VDC — no moving electrical parts to corrode or wear.

Polypropylene wetted construction

Compatible with water, mild acids/caustics, detergents, plating rinses, and aqueous process fluids to 180°F continuous.

ERECTA SWITCH modularity

Every component — float, stem, bulkhead, receptacle — is a stocked, field-replaceable part. No custom fabrication, no lead-time penalty on spares.

Applications

Specific installation scenarios that match the 10-785-PP configuration.

Low-clearance coolant reservoir level monitoring in CNC machining centers where overhead enclosures block top access
Side-wall level detection in stacked semiconductor rinse tanks
Condensate collection level alarm on commercial HVAC units with sealed top enclosures
Overflow prevention in plating line work tanks with full-surface spray bars
Retrofit level sensing in existing process tanks where drilling the top is not an option

Frequently Asked Questions

Common Questions About This Product

What is the difference between a float level switch and a liquid level sensor?

A float level switch like the 10-785 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.

What are the typical applications for the 10-785?

The 10-785 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.

What liquid chemistries is the 10-785 compatible with?

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.

Is the 10-785 a point-level or continuous-level device?

The 10-785 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.

What mounting options are available for the 10-785?

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.

How is the actuation level set on the 10-785, and how accurate is it?

Point detection is repeatable and mechanical. The trip height on the 10-785 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.
