MICRO SWITCH Premium Subminiature Basic Switches

SM Series

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

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.
