Honeywell 111SM248 Basic Switch Profile
The Honeywell 111SM248 basic switch sits within the MICRO SWITCH SM Series, a range known for combining compact dimensions with precise snap-action behavior. This model is generally discussed as a roller-style SPDT subminiature switch, making it especially relevant when a moving mechanical part must trigger a reliable change of state without requiring a large switch package. The Honeywell 111SM248 basic switch is therefore best understood as a compact control component designed to support repeatable actuation in tightly engineered assemblies.
Technical Direction of the Honeywell 111SM248 Basic Switch
Published distributor references identify the Honeywell 111SM248 basic switch as a 5 A subminiature SPDT basic switch in the SM family, generally tied to roller actuation and solder-style termination. Broader SM Series documentation associated with this part family highlights long mechanical life up to 10,000,000 operations, a wide choice of contact options including silver and gold-plated variants, and approvals such as UL, CSA, ENEC, and CE across relevant listings. These details help explain why this model is often treated as a specification-grade switch rather than a generic commodity component.
Why Engineers Look at the 111SM248 Variant
In compact motion systems, a roller-based actuator can improve consistency where a cam or sliding surface repeatedly contacts the switch. That can reduce drag and smooth the actuation event. For that reason, the Honeywell 111SM248 basic switch is often evaluated in mechanisms where wear behavior and repeatability matter as much as electrical ratings. It is also part of a family that supports multiple actuator and contact combinations, which gives designers room to standardize around one switch platform.
The result is a basic switch that fits well into detailed mechanical design work, especially where compactness and dependable actuation are key requirements. For more about Honeywell, comparing actuator variants across the SM range usually reveals how the same switch family can serve very different motion profiles.
FAQ
What type of switch is the Honeywell 111SM248 basic switch?
It is generally categorized as a subminiature SPDT snap-action switch in the SM Series, commonly associated with roller-style actuation for compact mechanisms.
Why is the Honeywell 111SM248 basic switch relevant in precision equipment?
Because small changes in actuator style can strongly affect real-world performance. A roller configuration can improve contact behavior with moving machine parts and may support smoother mechanical engagement.
Does this switch family support long service life?
Yes. SM Series references commonly cite mechanical life up to 10,000,000 operations, which is one of the reasons these switches remain important in engineered electromechanical systems.
What is the main selection priority for this model?
The most important point is usually the actuator interface. Electrical ratings are essential, but the success of the switch in the field often depends on whether the roller geometry matches the real movement of the host mechanism.
