MICRO SWITCH Premium Subminiature Basic Switches
DESCRIPTION
MICRO SWITCH SX Series is a premium
subminiature snap-action switch from
the family of S series subminiature
basic switches. Although small in size,
the SX Series is rated for controlling
electrical loads ranging from logic-level/
computer-based circuits to limited
power-duty switching (up to 7 A/
250 Vac). The SX premium subminiature
switch package offers gold contacts for
low energy switching and bifurcated
gold contacts for maximum reliability.
Bifurcated contacts provide parallel
redundancy within the SX switch.
A wide variety of stainless steel levers
are available and when combined with
the subminiature package size, can
adapt the SX Series to a wide range of
applications. To enhance the versatility
of SX switches, the family is certified
to UL, CE, CSA, ENEC, MIL-PRF-8805,
FAA-PMA and UKCA for worldwide use.
The SX Series is the right choice for a
cost-effective premium subminiature
switch package.
FEATURES
APPLICATIONS
• Industry-leading life cycle of up to
10,000,000 operations
• Selection of actuation, electrical
termination, and operating
characteristics
• Wide temperature range of -54°C to
204°C [-65°F to 400°F]
• Built from military-grade components
• MIL-PRF-8805 qualified listings
• Available with FAA-PMA approvals for
commercial aircraft applications
• Silver, gold-plated, or bifurcated gold
contacts to handle a variety of
electrical load requirements
• Available worldwide through
Honeywell’s network
• 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
• In precision switch assemblies for
pressure switches and temperature
switches
• In power generation, fuel level switch
for gas and oil
DIFFERENTIATION
• 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
