DESCRIPTION
Honeywell’s MICRO SWITCH ZD Series is a sealed
subminiature snap-action switch. Although small in size, the
ZD Series is rated for controlling electrical loads ranging from
logic-level (low current, low voltage) to limited power-duty
switching (up to 3 A/125 Vac).
The switch when provided with integral wire leads is sealed
to IP67 and is suitable for applications where the switch
assembly would be exposed to liquids or particulate
contaminates in the environment.
A wide variety of stainless steel levers are available, and when
combined with the subminiature package size, can adapt
the switch for many different applications. The ZD Series is
certified to UL, cUL, ENEC, and CQC for worldwide use.
Electric window control for automobiles
Automobile seat belt latch detection
Engine hood or trunk latch detection
Vehicle door latch detection
Vehicle mounted wheelchair lifts
VALUE TO CUSTOMERS
• Well suited for power-duty and logic-level loads
• Performs in wet, dirty, and dusty environments
• Enhances safety through enablement of monitoring and
guidance capabilities that improve productivity of operators
PORTFOLIO
The ZD Series of subminiature basic switches are a part
of a strong offering of submins including ZM/ZM1 , ZX, and
ZW Series switches.
DIFFERENTIATION
• The IP67-rated ealed switch is designed to operate in a
variety of demanding applications, reducing the challenge of
harsh environments
• Current carrying capacity, up to 3 A, allows for a solution in
many applications where space is a premium
• Switch package designed to accommodate demanding
temperature requirements, up to 85 °C [185 °F]

NOTES:
1
Not all combinations of model code are available. Please contact your Honeywell provider/representative for assistance.
2
Terminal Type “99”, Actuator Type “S”, and/or Pillar/Travel Type “99” designates a special and requires a special designation at the end of the listing.
3
Operate force is measured at the plunger. Adding an actuator/lever will change the operate force. See page 6 for operate force.
4
Standard wire exit is out the bottom of the switch. No special designator is necessary for this wire exit direction.
5
SPNO and SPNC are only available if termination type is wired.
6
Standard wire length is 500 mm [19.5 in] long. Other lengths available upon request.
7
Long solder terminals do not have UL or ENEC approvals.
8
Switches with AVSS wire do not have UL approvals.
9
Long and short travel pertain to plunger travel distance. Short travel has a taller boss around the plunger to limit overtravel.
