Honeywell 111SM241 Basic Switch Explained
The Honeywell 111SM241 basic switch is part of the MICRO SWITCH SM Series, a subminiature switch platform known for compact size and reliable snap action. This specific version is typically identified as a roller lever SPDT switch with solder termination, which makes it especially relevant in mechanisms where movement is transferred through a cam, wheel, or sliding component. The Honeywell 111SM241 basic switch is therefore not only an electrical component, but also a mechanical interface point in many compact devices.
Technical Features of the Honeywell 111SM241 Basic Switch
Available product data describes the Honeywell 111SM241 basic switch as a chassis-mount SPDT snap-action switch rated at 5 A, with 250 V AC and 30 V DC capability. Distributor listings also point to a roller lever actuator, solder lug termination, operating force around 170 gf, operating position near 14.3 mm, pretravel around 5.5 mm, and mechanical life up to 10,000,000 cycles. Its stated operating temperature range is commonly listed from -55 °C to 125 °C. Those details place it in the group of compact switches built for repeatable switching under defined mechanical conditions.
Why This Model Is Often Preferred in Compact Motion Systems
In many assemblies, a roller lever switch offers a practical advantage over direct plunger-only formats because it can follow moving surfaces with less abrasion and lower drag. That matters in equipment where the actuator contacts a cam or passing part over and over again. The Honeywell 111SM241 basic switch supports that kind of design logic while still maintaining the compact body size associated with subminiature basic switches.
The part also reflects the broader value of the SM Series: small dimensions, precise switching, and strong cycle life for long-term service. For more about Honeywell, it is worth exploring how similar SM Series variants differ only by actuator or termination style, allowing a consistent mechanical architecture across multiple products.
FAQ
What kind of actuator does the Honeywell 111SM241 basic switch use?
It is generally listed with a roller lever actuator. That style is useful when a moving machine element needs to engage the switch smoothly and repeatedly without excessive friction.
Is the Honeywell 111SM241 basic switch suitable for compact equipment?
Yes. It belongs to a subminiature switch family, so one of its main strengths is its ability to fit into space-constrained assemblies while still providing solid electrical ratings and a defined snap-action response.
Why does operating force matter in this model?
Operating force affects how easily the switch changes state when contacted by a moving part. In precision mechanisms, that force value helps determine whether the switch will respond consistently without overloading the actuator path.
What should maintenance teams pay attention to?
They should confirm the roller path, the mounting alignment, and the electrical load. In the field, premature issues often come from mechanical misalignment rather than from the switching element itself.
