ENTRELEC DL42N-22 – 22 mm Panel-Mount Selector Switch for Reliable Machine Control

The ENTRELEC DL42N-22 appears to be a 22 mm panel-mount selector switch configured with 2NO + 2NC contacts, designed for typical start/stop, mode change (Manual/Auto), or function selection on industrial control panels. From my experience, this form factor fits most OEM and retrofit panels without fuss, and the maintained two-position action gives clear, repeatable detents that operators trust on the line.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: 1 week for in-stock items; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• 22 mm standard cutout: Fits common IEC panel cutouts for quick drop-in replacement in most control panels.
• 2NO + 2NC contact set: Flexible wiring for interlocks, signaling, and PLC input redundancy.
• Maintained 2-position operation: Positive detents that help avoid accidental switching; operators feel the position clearly.
• Dry-contact signaling: Works with typical PLC/relay control circuits without external power to the device.
• Front-panel sealing (typical): In many cases rated up to IP65 at the operator face when installed with the supplied gasket.
• Screw-clamp terminals: Straightforward wiring for 0.5–2.5 mm² conductors commonly used in cabinets.
• Compact depth: Leaves space for cable routing and adjacent devices in dense enclosures.

Technical Specifications

Application Fields

You might notice that the DL42N-22 slots into a wide range of control schemes. It’s commonly used on:

• Machine tools and packaging lines for mode selection (Jog/Auto, Forward/Reverse)
• Conveyors and material handling panels for start/stop and direction control
• HVAC and building automation for fan mode and damper control selection
• Water/wastewater skids for pump lead/lag or local/remote selection
• Process panels where clear operator confirmation and durable contacts are required

Advantages & Value

• Compatibility: Standard 22 mm cutout simplifies retrofits and multi-vendor panels.
• Reliability: Positive mechanical detents reduce nuisance toggling in high-vibration cabinets.
• Cost control: Simple, serviceable contact blocks keep maintenance budgets predictable.
• Support-ready: From wiring diagrams to installation tips, we can help match your PLC I/O and safety logic.

One thing I appreciate is how straightforward it is to wire 2NO + 2NC for both signaling and permissive logic. A packaging OEM we serve keeps the DL42N-22 as a standard part because—after hundreds of units—operators still comment on the crisp feel and fewer accidental changes in mode.

Installation & Maintenance

• Panel prep: 22 mm round cutout; ensure clean edges and install the gasket for front sealing.
• Mounting: Seat the operator and tighten the fixing nut evenly; avoid over-torque that could distort the bezel.
• Wiring: De-energize the panel; use appropriately sized ferrules; tighten screw clamps and perform a tug test on each conductor.
• Ventilation: Keep adequate spacing to avoid cable strain and allow heat dissipation in compact enclosures.
• Safety: Verify correct contact states with a multimeter before commissioning; label positions clearly at the panel.

• Routine checks: Inspect detent feel, re-tighten terminals during scheduled maintenance, and clean the operator face if exposed to oils or dust.
• Spares management: Keeping spare contact blocks on hand typically minimizes downtime during shift-change repairs.

Quality & Certifications

• Compliance (typical): IEC 60947-5-1; CE marking; commonly supplied with UL and RoHS conformity for industrial control components.
• Warranty: 12 months from delivery (365 days).

If you’re matching this to an existing panel standard, share your contact ratings and preferred terminal style—I can verify the DL42N-22 configuration and propose a compatible alternative if your project needs a specific actuator color or key-operated version.
