MICRO SWITCH™ Premium Subminiature Basic Switches SX Series Datasheet
MICRO SWITCH™ SX Series Premium Subminiature Basic Switches The industry-defining name in snap-action switches, Honeywell MICRO SWITCH™ premium subminiature switches are designed for repeatability and enhanced product life. The MICRO SWITCH™ SX Series delivers consistent performance within a range of conditions. Offering enhanced repeatability, the MICRO SWITCH™ SX Series’ lower operating force provides for application versatility.
Features and Benefits LONG LIFE With a mechanical life of up to 10,000,000 operations, SX Series switches boast an industry-leading life cycle. APPLICATION FLEXIBILITY MICRO SWITCH™ SX Series delivers a selection of actuation, electrical termination, and operating characteristics along with high-temperature construction options.
Potential Applications AEROSPACE • In precision switch assemblies for commercial aircraft to monitor doors for “closed” and “locked” position • Monitor whether landing gear is “up” or “down and locked” • In precision switch assemblies for commercial cockpit applications for pushbuttons, toggle, or joystick assemblies • MIL-PRF-8805 listings suitable for precision switch assemblies in military applications • FAA-PMA approvals for commercial aircraft INDUSTRIAL • In precision switch assemblies for pressure s
