DESCRIPTION
VALUE TO CUSTOMERS
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 SM Series delivers consistent performance
within a range of conditions.
The MICRO SWITCH SM Series’ small size and light weight are
combined with ample electrical capacity, precision operation,
and extended life. Featuring high precision and repeatability,
the SM Series offers gold contacts for low-energy switching
and gold bifurcated contacts for maximum reliability.
Bifurcated contacts provide parallel redundancy within the SM
switch.
The SM switch is available for power-duty switching up to 11 A
(Vac) or 1/4 HP (Vac).
• Industry-leading life cycle rating reduces the need to
replace switches over life in an OEM platform – reducing
total system cost
• Low operating forces
• Mil-qualified listings
• Life of up to 10,000,000 cycles
POTENTIAL APPLICATIONS
DIFFERENTIATION
• Precision switch assemblies for commercial aircraft to
monitor doors for “closed” and “locked” position
• Landing gear monitor
• Precision switch assemblies for commercial cockpit
applications for pushbuttons, toggle, or joystick assemblies
• Precision switch assemblies in military applications
• Assemblies for industrial pressure switches and temperature
switches
• Power generation fuel level (gas and oil)
• 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 0,06 N [6 g] and differential travel
as low as 0,025 mm [0.001 in] delivers consistent, precise
switch characteristics
The SM Series of premium subminiature basic switches are
a part of a strong offering of submins including SX Series
(premium) and ZM, ZM1, ZD, ZX, and ZW Series (standard)
switches.
