MICRO SWITCH™ SX Series
Premium Subminiature Switch
DESCRIPTION
The industry-defining name in snap-action switches, Honeywell
MICRO SWITCH™ premium subminiature switches are designed
for repeatability and enhanced product life. MICRO SWITCH™
SX Series delivers repeatability and consistent performance
within a range of conditions.
Offering enhanced repeatability, MICRO SWITCH™ SX Series’
lower operating force provides for enhanced operation and ap-
plication versatility. Its covered case construction with molded-in
terminals allows for very simple adaptation to the customers’
actuation systems.
