What makes our switches better?
Small size and universal mounting footprint typically allows for use
in constricted spaces and reduces replacement costs by providing
interchangeability with similar style switches
Wide variety of actuator heads and an assortment of actuators
typically allows the SZL-WL Series to be applied in many types of
applications
IP67 construction often allows for use in dusty and dirty indoor
and outdoor applications
Mechanical service life of up to 10,000,000 operations promotes
the durability required for use in many types of industries from
factory floor to agriculture and/or machinery
MICRO SWITCH™ SZL-WL Series
General Purpose Limit Switches
MICRO SWITCH™ SZL-WL Series general purpose limit switches are cost effective switches that may be used in
a wide range of applications from general purpose conveyors to heavy-duty machinery. Rugged and reliable, the
SZL-WL Series switches are specially designed for world-wide use and supported by Honeywell’s vast experience in
serving industries around the globe.
High quality product offerings combined with Honeywell’s global sales and service resources makes the SZL-WL
Series the smart choice for industries whose goal is to minimize plant downtime and reduce overall maintenance
costs.

and Benefits
Features
and Benefits
INDUSTRIAL GLOBAL DESIGN
The SZL-WL Series is designed to the EN50041 mounting standard which
promotes interchangability between other brands of limit switches.
TWO CIRCUIT DOUBLE BREAK CONTACTS
The SZL-WL Series promotes reliable switching under industrial 10 amp current
loads and typically allows end users the ability to control two circuits within one
switch.
WIDE CHOICE OF ACTUATORS
Honeywell’s SZL-WL Series offers side rotary, top and side plunger, and wobble
stick style actuators that makes the switch reasonably adaptable to numerous
types of applications.
OIL TIGHT, WATER TIGHT, DUST TIGHT
IP67 sealing protects against dust and moisture, and allows the SZL-WL Series
to be used in dirty and rugged environments found in both indoor and outdoor
applications.
Robust and reliable.

Proper Operation Zone
• The two convex indicators on the shaft housing show the
operating zones for proper operation, thereby, simplifying
installation and maintenance.
• Too much over-travel may cause shortened mechanical life
due to possible damage to the switch mechanism.
