Honeywell 111SM244 Basic Switch Guide
The Honeywell 111SM244 basic switch is a subminiature snap-action switch in the SM Series, designed for users who need a compact SPDT solution with a straight lever style actuator. In practical use, this switch is often associated with equipment where a moving linkage or controlled travel path actuates the lever with a clear mechanical motion. Because of that, the Honeywell 111SM244 basic switch often appears in engineering discussions around compact industrial controls, machine subassemblies, and precision electromechanical interfaces.
Technical Highlights of the Honeywell 111SM244 Basic Switch
Available product data identifies the Honeywell 111SM244 basic switch as an SPDT chassis-mount switch with a straight lever actuator, solder lug termination, 5 A current rating, 250 V AC rating, and 30 V DC rating. Detailed distributor specifications also reference an operating force of about 198 gf, a release force around 57 gf, operating position near 8.9 mm, and mechanical life up to 10,000,000 cycles. Additional technical sources describe this version as using an integral flexible leaf with straight lever actuation and high-temperature construction up to 204 °C in certain datasheet descriptions.
Why the Straight Lever Version Is Important
Not every switch application suits a roller or plunger. A straight lever can be the better choice when the actuating part travels along a more direct path or when system designers want a predictable contact point along the lever arm. That makes the Honeywell 111SM244 basic switch a useful option in designs where the lever geometry is part of the switching strategy, not just a packaging detail.
Within the SM Series, this model also reflects a broader design principle: compact dimensions paired with respectable electrical capacity and long cycle life. For more about Honeywell, it is helpful to compare this switch with roller-lever SM variants, since the main difference is often mechanical behavior rather than the core switching platform.
FAQ
What actuator style does the Honeywell 111SM244 basic switch use?
It is commonly listed as a straight lever version. That matters because lever shape influences how force is applied and where the switch changes state in the overall mechanism.
Is the Honeywell 111SM244 basic switch a momentary switch?
Yes. It is generally described as an SPDT snap-action switch with momentary switching behavior, meaning the contact state changes according to actuator position rather than locking mechanically in place.
Why do engineers compare this model with roller lever switches?
Because the internal switching class may be similar, but the actuator style changes the mechanical interface. In real-world design, that difference can affect wear, travel path, force distribution, and repeatability.
Does the 111SM244 belong to a high-cycle switch family?
Yes. The SM Series is commonly associated with long mechanical life, and this model is routinely listed with cycle-life figures up to 10,000,000 operations, which is an important benchmark for repetitive-use equipment.
