Snap-Action Switches
Honeywell Sensing and Control 3
SERIES ZW (water-tight) ZD (water-tight) ZX
Differentiator IP67 rating with lead wires;
snap-on lever, coil spring, and
ENEC
Smaller sized (like the ZX),
sealed to IP67 (with leadwires
only); plunger travel can be
restricted, offers side-post quick
mounting
Two-thirds the size of the ZM
Series; unsealed, integral lever,
and coil spring
Use Use when a sealed position
switch in a small and cost-
effective package is required
Use for automotive applications
due to sealing and quick
mounting option
Use when a much smaller
unsealed position switch is
required
Potential
applications
air conditioners, computers,
consumer appliances, gas
detectors, joysticks, money
sorters, telephones, toys
automotive (operation systems
and engine area interior), air
conditioners, communication,
