Honeywell 11SX47-H58 Basic Switch: Technical Guide for Precision Applications
The Honeywell 11SX47-H58 basic switch is a specialized SX Series snap-action switch developed for compact applications that require precise switching behavior and dependable electrical performance. Compared with more standard SX variants, the 11SX47-H58 electromechanical switch stands out because of its lower current rating, quick connect termination, and gold-plated contact design.
Technical Specifications of the 11SX47-H58 Basic Switch
The Honeywell 11SX47-H58 basic switch uses an SPDT circuit and a round pin plunger actuator. It is rated at 3 A AC with a 250 V AC voltage rating and uses quick connect termination. The switch is chassis mounted and works in an operating temperature range of -55°C to 125°C. Mechanical life is listed at 10,000,000 cycles, supporting long-term repeatability in demanding mechanical systems.
A key difference is the contact design. Published product data describes the Honeywell 11SX47-H58 basic switch as using gold-plated contacts and notes special air gap and differential travel characteristics. It also has a very fine 0.013 mm differential travel, which is significantly tighter than broader-purpose variants. In practice, that matters in sensitive control environments where switching accuracy and contact reliability are more important than general-purpose load handling.
Best Use Cases for the 11SX47-H58 Electromechanical Switch
The Honeywell 11SX47-H58 switch is relevant for compact precision equipment, low-level control circuits, highly repeatable motion-triggered assemblies, and engineered systems that benefit from gold-plated contacts. While not every application requires that contact style, it can be valuable in designs where signal integrity or switching consistency is a higher priority than maximum current capacity.
Because of its SX Series architecture, the 11SX47-H58 basic switch still supports the familiar compact Honeywell form factor. For more information about Honeywell, it is worth comparing this model with other SX Series options when selecting by current rating, contact material, and terminal type.
Why the Honeywell 11SX47-H58 Basic Switch Is Distinct
The combination of 3 A at 250 V AC, gold-plated contacts, quick connect termination, and very small differential travel makes the Honeywell 11SX47-H58 electromechanical switch a more specialized choice within the SX family. That profile makes it especially suitable where precise actuation and stable low-level switching characteristics are central to product reliability.
