Honeywell 11SM1-T Basic Switch Overview
The Honeywell 11SM1-T basic switch is a subminiature snap-action switch designed for dependable switching in compact electromechanical systems. As part of the Honeywell SM Series, the Honeywell 11SM1-T basic switch is often selected for applications where consistent operation, defined travel values, and compact packaging all matter. It is frequently researched using terms such as Honeywell 11SM1-T basic switch, Honeywell 11SM1-T micro switch, and Honeywell 11SM1-T SPDT switch.
Technical Specifications of the Honeywell 11SM1-T Basic Switch
The Honeywell 11SM1-T basic switch features an SPDT circuit and a round pin plunger actuator. It is rated for 5 A at 250 V AC and 30 V DC, making it suitable for a broad range of compact switching duties in industrial and commercial equipment. This model is configured for chassis mount installation and uses solder turret termination, which is often preferred when secure point-to-point wiring is required.
Its mechanical performance is defined by an operating force of 141 gf, a release force of 28 gf, 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). These values help engineers model the switching point accurately and make the Honeywell 11SM1-T micro switch a reliable option for precise mechanical interaction.
Application Value of the Honeywell 11SM1-T Basic Switch
The 11SM1-T SPDT switch is commonly used in compact industrial controls, sensing interfaces, instrumentation modules, enclosure assemblies, and other products where repeatable contact switching is important. It offers a rated mechanical life of 10,000,000 cycles, which supports designs expected to operate repeatedly over long service intervals.
The temperature range of -55°C to 125°C expands its usefulness in systems that see cold starts, internal heat buildup, or fluctuating ambient conditions. In many applications, this means the switch can provide reliable long-term performance even when the surrounding environment is not ideal.

FAQ
What type of terminal does the Honeywell 11SM1-T basic switch use?
It uses solder turret termination, which is commonly chosen for robust wired connections in compact chassis-mounted assemblies. This terminal style is helpful when designers need a firm electrical connection and controlled wiring layout.
Why is the 11SM1-T micro switch popular in compact equipment?
It offers a useful balance of compact size, 5 A switching capacity, long mechanical life, and predictable travel characteristics. That combination makes it practical in devices where both performance and space efficiency are critical.
Is the 11SM1-T SPDT switch suitable for repetitive mechanical action?
Yes. Its 10 million cycle mechanical life supports repeated actuation over extended use. In equipment that opens, closes, or cycles regularly, that durability is an important benefit.
What should be checked before replacing a Honeywell 11SM1-T basic switch?
Engineers usually confirm actuator style, mounting configuration, force values, terminal type, and travel data before replacement. Matching only the current rating is not enough when the switch is part of a precise mechanical assembly.
