MICRO SWITCH™ Standard
Subminiature Snap-Action
Z Series
Snap-Action Switches
0BDESCRIPTION
The industry-defining name in snap-action switches, Honeywell
MICRO SWITCH™ standard subminiatures are designed for
repeatability and enhanced product life. The MICRO
SWITCH™ Z Series combines small size and light weight with
ample electrical capacity, low cost, and enhanced life.
The MICRO SWITCH™ Z Series consists of six product
families with unique features that can drop right into an
application.
These reliable and rugged switches offer a variety of actuators,
terminations, circuitry configurations, electrical ratings, contact
materials, operating characteristics, and sealing allows them to
be utilized in numerous potential applications.
Carefully manufactured and thoroughly inspected, the MICRO
SWITCH™ Z Series standard subminiatures are a great value
for applications requiring sensing presence or absence of an
object.
FEATURES
• Small size and light weight switches lend themselves to
numerous potential applications
• Choice of low energy or power-duty electrical ratings allow
the switch to be specified in more types of applications
• Broad range of amp ratings (from 0.1 A to 10.1 A)
• Watertight IP67 sealing available on some listings allows
the switch to be used where sealing and presence/absence
detection is required
• UL/CSA, cUL, ENEC, and CE approvals
POTENTIAL APPLICATIONS
• Industrial: Appliances, communication equipment,
computers, electromechanical timers, mechanical cam
assemblies (timers), office equipment, electric tools, HVAC
wall controls, instrumentation, valves, vending machines
• Transportation: Automotive, truck, and boat wire
harnesses; sub-assemblies for convertible roofs; lock
modules for tail-gate/trunk; tank and hood latch detection
• Medical: Medical and hospital beds, foot pedal controls,
and chair lifts
• Applications where a pre-wired sealed on/off switch is
required
