Product Description

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).
 

DIFFERENTIATION

• 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

 

FEATURES

• Industry-leading mechanical life of up to 10,000,000 operations

• Selection of actuation, electrical termination, and operating characteristics along with high-temperature construction options

• Wide temperature range of -54°C to 204°C [-65°F to 400°F]

• MIL-PRF-8805 qualified listings in a lightweight, small package

• FAA-PMA approvals for commercial aircraft

• Choice of silver or gold-plated, or gold bifurcated contacts to handle a variety of electrical load requirements

• UL/CSA, cUL, ENEC, and CE approvals
 

VALUE TO CUSTOMERS

• 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

• 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)

PORTFOLIO
