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.
Like the MICRO SWITCH™ SM Series, the SX Series (which is a smaller package) offers gold contacts for low energy
switching and bifurcated gold contacts for maximum reliability. Bifurcated contacts provide parallel redundancy within the
SX switch.
What makes our switches better?
• Industry-leading life cycle rating reduces the need to replace
switches over life in an OEM platform – reducing total
system cost
Very wide temperature range allows for years of reliable
performance in the harshest of conditions
MIL-PRF-8805 qualified listings
Operating forces as low as 0,147 N [15 g] and differential
travel as low as 0,025 mm [0.001 in] delivers consistent
precise switch characteristics
Small in size,
large in capability!
COST OPTIMIZATION • PERFORMANCE
RELIABILITY • GLOBAL ACCEPTANCE

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.
Life of up to 10,000,000 cycles
INDUSTRY-LEADING TEMERATURE RANGE
With a wide temperature range of -54 °C to 204 °C [-65 °F to 400 °F],
SX Series switches allow for years of reliable performance in harsh
conditions.
Precision switch characteristics
COMPACT AND ROBUST
Built from military-grade components, MICRO SWITCH™ SX switches
deliver MIL-PRF-8805 qualified listings in a lightweight, subminiature package.
SX switches are available with FAA-PMA approvals for commercial aircraft
applications.
EASILY CONTROLS LOW-VOLTAGE DC APPLICATIONS
Switches available with a choice of silver, gold-plated, or bifurcated gold
contacts to handle a variety of electrical load requirements.
GLOBAL APPROVALS
UL/CSA, cUL, ENEC, and CE approvals allows the customer to utilize switches
in products sold across the globe - in some of the most regulated regions.

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 switches and temperature switches
• In power generation, fuel level switch for gas and oil
