Honeywell 11SM712-H58 Basic Switch Overview for Compact SPDT Control
The 11SM712-H58 basic switch is a subminiature electromechanical switch developed for compact systems that still need dependable snap-action performance. In many control and sensing applications, engineers look for a switch that is small, repeatable, and easy to integrate. The 11SM712-H58 electromechanical switch answers that requirement with an SPDT configuration, a pin plunger actuator, and quick connect termination.
Understanding the Honeywell 11SM712-H58 Basic Switch
This model belongs to Honeywell’s SM Series of subminiature basic switches. It is designed as an SPDT on-momentary switch and typically appears in assemblies where mechanical movement must be translated into an electrical signal with high consistency. Because it uses a chassis-mount format, it can be integrated into a wide variety of device housings and machine structures.
Technical Features That Matter
The Honeywell 11SM712-H58 basic switch is commonly specified at 5 A for AC/DC loads, with rated voltages up to 250 V AC and 30 V DC. It uses a round pin plunger actuator and quick connect termination sized at 0.058 inch. Typical operating force is 56 gf, release force is 14 gf, operating position is around 8.4 mm, and pretravel is 0.5 mm. Differential travel is approximately 0.05 mm, while overtravel is about 0.13 mm. Mechanical life is listed up to 10,000,000 cycles, and the operating temperature range is approximately -55°C to 125°C.
Typical Applications
The Honeywell 11SM712-H58 basic switch is well suited to industrial equipment, compact mechanism monitoring, control panels, instrumentation devices, and electromechanical assemblies where precise actuation is needed. Quick connect termination can also be useful in designs that benefit from efficient serviceability or streamlined assembly processes.
Why This Honeywell Electromechanical Switch Stands Out
Many designers choose a Honeywell SM Series switch because of its predictable mechanical behavior and broad environmental capability. With the 11SM712-H58, the value lies in how it combines compact dimensions, practical electrical capacity, and a familiar actuator format. That combination makes it a reliable option for applications that need long-term switching consistency without moving to a larger switch family.
For OEMs and maintenance teams alike, the 11SM712-H58 basic switch represents a practical component choice when durability, compact size, and repeatability are more important than unnecessary complexity.
FAQ
What is the Honeywell 11SM712-H58 used for?
It is used in compact electromechanical systems for position detection, snap-action control, and status signaling. Common environments include industrial machines, instrumentation, and control assemblies.
What contact arrangement does the Honeywell 11SM712-H58 basic switch have?
It uses an SPDT contact configuration, which gives designers flexibility for normally open and normally closed circuit logic within a single switch body.
Does the Honeywell 11SM712-H58 support quick wiring?
Yes. One of the defining features of this model is its quick connect termination style, which can simplify installation and maintenance in the right assembly design.
How durable is the 11SM712-H58 electromechanical switch?
This model is generally listed with a mechanical life of up to 10 million cycles. That makes it suitable for repeated actuation in applications where long service life is expected.
Is the 11SM712-H58 a good fit for demanding environments?
It can be. Its operating temperature range down to -55°C and up to 125°C makes it relevant for applications exposed to broader environmental variation than standard indoor electronics.
