Snap-Action Switches
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),
Two-thirds the size of the ZM
Series; unsealed, integral lever,
and coil spring
sealed to IP67 (with leadwires
only); plunger travel can be
restricted, offers side-post quick
mounting
Use
Use when a sealed position
switch in a small and cost-
effective package is required
air conditioners, computers,
consumer appliances, gas
detectors, joysticks, money
sorters, telephones, toys
