Omron D2SW-3L1HS Snap Action Switch Spdt 3A Hinge Lever

Product Description

The OMRON D2SW-3L1HS is a sealed miniature snap action switch rated for SPDT switching in low-voltage control and signal circuits. It features a hinge lever actuator and solder terminal connections, making it a compact, field-replaceable component for equipment where space is limited and reliable switching is required. Rated at 3 amps at 125 VAC, 2 amps at 250 VAC, and 3 amps at 30 VDC, the D2SW-3L1HS handles a range of AC and DC load requirements. The sealed construction protects internal contacts against contamination, and the silver-plated contacts support consistent electrical performance across repeated cycles.

This switch is suited for use in HVAC controls, refrigeration equipment, small appliance interlocks, and industrial control panels where a miniature snap action switch with a hinge lever is specified. The SPDT contact configuration provides both normally open and normally closed outputs from a single device, giving the installer flexibility in control circuit wiring. Its compact dimensions of 0.47 inches high by 0.78 inches long by 0.25 inches wide allow installation in tight enclosures and panel cutouts. The rated operating temperature range of -13 degrees F to 185 degrees F covers most indoor HVAC and light industrial applications.

Key Features

• SPDT contact form with NO and NC outputs from a single switch body
• Hinge lever actuator with a maximum operating force of 2.12 ounces
• Sealed miniature construction resists contamination at contact surfaces
• Silver contact plating for reliable switching over extended service life
• Solder terminal connection type for direct PCB or hardwired installation
• Certified to CSA, UL, and IEC 529 standards

Compatibility

Designed as an OEM-style replacement miniature snap action switch for HVAC controls, refrigeration equipment interlocks, and industrial control panel applications requiring a sealed SPDT hinge lever switch with solder terminals.

Installation Notes

Installation should be performed by a qualified electrician or controls technician familiar with low-voltage switching circuits. De-energize all power to the control panel or equipment before replacing or installing this switch. Solder connections should be made with appropriate flux-core solder and proper heat management to avoid damaging the switch body or nearby components. Consult applicable NEC guidelines for control circuit wiring practices.
