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
