Honeywell 11SM1077-H58 Basic Switch Overview
The Honeywell 11SM1077-H58 basic switch is a precision subminiature snap-action component developed for low-current switching applications that still require dependable mechanical performance. This model belongs to the Honeywell SM Series and is frequently researched under search phrases such as 11SM1077-H58 basic switch, Honeywell 11SM1077-H58 micro switch, and Honeywell 11SM1077-H58 SPDT switch. It is especially relevant in compact equipment where low-energy switching and stable actuation characteristics matter.
Technical Specifications of the Honeywell 11SM1077-H58 Basic Switch
The Honeywell 11SM1077-H58 basic switch features an SPDT contact arrangement with a round pin plunger actuator. It is rated for 100 mA at 125 V AC and 30 V DC, positioning it as a suitable option for signal-level or low-power switching rather than higher-current load handling.
This version uses a quick connect 0.058 in round termination and a chassis mount format. The operating force is 141 gf, while the release force is 28 gf. It also provides a pretravel of 0.020 in (0.5 mm), differential travel of 0.004 in (0.1 mm), overtravel of 0.005 in (0.13 mm), and an operating position of 0.330 in (8.4 mm). The mechanical life reaches 10,000,000 cycles, which is a strong indicator of durability in repetitive-use systems.
Application Perspective
The Honeywell 11SM1077-H58 basic switch is often considered for control circuits, compact industrial assemblies, instrumentation devices, and electromechanical subsystems where switching repeatability is more important than high current capacity. In practical design work, this is the kind of switch engineers choose when they need compact dimensions and predictable actuation in a low-power circuit path.
Its operating temperature range of -55°C to 125°C supports deployment in equipment exposed to varying environmental conditions. One detail worth noting is that some distributors list the Honeywell 11SM1077-H58 basic switch as obsolete, so engineers usually verify availability before finalizing it in new production designs.

FAQ
What is the main advantage of the Honeywell 11SM1077-H58 basic switch?
Its biggest advantage is the balance between compact size and precise low-current switching. For signal-level applications, the switch gives designers a reliable mechanical response without moving to a larger switch platform.
Is the Honeywell 11SM1077-H58 micro switch intended for power switching?
Not primarily. With a rating of 100 mA at 125 V AC and 30 V DC, it is better suited to low-energy control, sensing, and logic-related switching tasks. It is not the usual choice for heavier electrical loads.
Why is the quick connect terminal style important on the 11SM1077-H58 SPDT switch?
Quick connect terminations can simplify serviceability and assembly depending on the product design. In applications where maintenance access matters, this format may reduce wiring time compared with some permanent connection methods.
Should the 11SM1077-H58 basic switch be used in new designs?
It can still be relevant in service, repair, or exact replacement scenarios, but because some distributors identify it as obsolete, engineers often verify lifecycle status and compare it with currently active Honeywell alternatives before choosing it for a new platform.
