Honeywell 11HM25N-REL-PGM Sealed Basic Switch
The Honeywell 11HM25N-REL-PGM sealed basic switch is associated with Honeywell’s hermetically sealed switch technology and is publicly listed as an SPDT basic switch rated at 3 A with catalog references to 115 Vac and 28 Vdc. Available drawing and product data also connect this part with hermetic construction, corrosion-resistant exposed materials, tinned terminals for soldering, and a dry nitrogen fill. That combination makes the Honeywell 11HM25N-REL-PGM hermetic switch especially relevant where environmental isolation and stable switching behavior are essential.
What Honeywell 11HM25N-REL-PGM Is Built For
The Honeywell 11HM25N-REL-PGM sealed basic switch is intended for applications that need dependable electromechanical switching in environments that may include contamination, vibration, humidity, or aggressive atmospheric conditions. Hermetically sealed switch construction is often chosen when engineers want to protect internal contacts from external influences that can shorten service life or affect switching consistency.
Technical Characteristics of the 11HM25N-REL-PGM
Public catalog and drawing sources identify the Honeywell 11HM25N-REL-PGM as an SPDT switch with a 3 A electrical rating and hermetic sealing based on metal-to-metal and glass-to-metal construction. Additional published notes mention a temperature range from about -300 °F to +250 °F, corrosion-resistant exposed materials, and solder-ready tinned terminals. While exact application requirements should always be checked against the original part documentation, these characteristics clearly position the switch for demanding sealed-switch applications.
Why 11HM25N-REL-PGM Matters
Searches for Honeywell 11HM25N-REL-PGM sealed basic switch, SPDT hermetic switch, 3A sealed microswitch, and Honeywell harsh environment switch often reflect real engineering needs rather than casual product browsing. In many systems, the switch must not only meet the circuit requirement but also maintain reliable performance in conditions where open or lightly protected switches may fail prematurely.
What to Verify Before Replacing It
Before specifying the Honeywell 11HM25N-REL-PGM hermetic sealed switch, engineers should confirm lever style, terminal arrangement, mounting dimensions, electrical load, and any environmental or qualification requirements. This is especially important where the original switch is part of a qualified assembly or a harsh-environment design.
FAQ
What type of switch is Honeywell 11HM25N-REL-PGM?
