Honeywell 141SM102-T Subminiature Basic Switch Guide
The Honeywell 141SM102-T basic switch belongs to Honeywell’s SM Series of premium subminiature snap-action switches. This product type is widely used when designers need compact dimensions, dependable switching behavior, and predictable mechanical response in control assemblies. The Honeywell 141SM102-T subminiature basic switch is especially relevant in equipment where space is limited but electrical performance and repeatable actuation still matter.
Technical Highlights of Honeywell 141SM102-T
Public distributor specifications identify the Honeywell 141SM102-T switch as an SPDT snap-action switch with 11 A AC and 5 A DC current ratings, up to 250 V AC and 30 V DC. The actuator is commonly listed as a round pin plunger, and the switch uses solder turret termination with chassis mounting. Additional published values include an operating force of 141 gf, pretravel of 0.030 in, differential travel of 0.004 in, and an operating temperature range of -55°C to 125°C.
Why the SM Series Remains Important
Honeywell’s SM Series is known for compact size, light weight, and precision operation. The official family documentation also emphasizes high repeatability and small operating tolerances, helping engineers maintain consistent switching behavior in tightly controlled mechanisms. A Honeywell 141SM102-T basic switch product type is a strong fit where designers need dependable snap action without moving up to a larger form factor.
Common Application Areas
The Honeywell 141SM102-T subminiature basic switch can be used in industrial controls, instrumentation, electromechanical assemblies, appliance subsystems, and compact equipment interfaces. In these environments, a switch is not just an electrical part. It is also a mechanical input element, so operating force, travel, and mounting style all shape the end-user experience and the consistency of the mechanism.
Because this model combines a compact body with solid electrical ratings, it is often attractive in designs that need both precision and durability. For more information about Honeywell, reviewing the wider SM Series can help compare actuator and terminal options.
