Procurement Notes

Verify the specific actuator style and contact material configuration against the official datasheet before procurement. Confirm RoHS compliance status and any recent Product Change Notifications (PCNs) that may affect form, fit, or function. Ensure the ordering suffix matches the required terminal type and lever configuration exactly as specified in the manufacturer's documentation.

Selection Notes

Select this component when high repeatability and extended operational life are critical. The SM Series provides precision operation suitable for low-energy switching with gold contacts or high-power duty with bifurcated options. Consider the wide temperature tolerance and compact footprint for space-constrained designs requiring robust snap-action performance under varying electrical loads.

Part Context

This part belongs to the MICRO SWITCH SM Series of premium subminiature basic switches. The series is defined by its small size, light weight, and ample electrical capacity. It is engineered for OEM platforms demanding consistent performance across a broad range of conditions, combining industry-defining reliability with versatile termination and actuation choices.

Replacement Considerations

Consult the official Honeywell cross-reference guide for verified substitutes. Ensure any replacement maintains the same SPDT configuration, voltage ratings, and actuator force characteristics to preserve system integrity.
