Drip-proof Switch (Z-@55)
• The Switch is not perfectly oil-tight; so do not dip it in oil or water.
• The rubber boots are made from weather-resistive chloroprene
rubber.
• Do not use Basic Switches in places with radical changes in
temperature.
• Rubber boots and rubber caps will tend to harden at lower ambient
temperatures. If an Actuator is used in a pressed state for an
extended period of time at low temperatures, it may return slowly or
it may not return at all. OMRON can provide special Actuators for
use at low temperature with rubber boots or rubber caps made of
silicon rubber, which has superior resistance to cold. Ask your
OMRON representative for details.
Split-contact Switch (Z-10F@Y)
The applicable current varies depending on how the contacts are
used. If the Switch is connected in series, the Switch can endure a
current 1.5 to 2 times higher than the current that can be applied in
parallel connection.
Flexible Rod Switch (Z-15@NJ@55, Drip-proof)
• When the rod is fully swung, the Switch may operate when the lever
returns, causing chattering. Use a circuit that compensates for
chattering wherever possible.
• Do not switch the rod to the fullest extent when the Switch is to
break a power circuit because such a practice may cause metal
deposition to occur between the mating contacts of the Switch.
Other Precautions
• Do not apply excessive force with a screwdriver or other tool when
attaching or removing the Protective Cover. Doing so may deform
the Switch.
• The Drip-proof Terminal Protective Cover can be sued only with
Switches with model numbers ending in “-B5V.”
• Only the Terminal Protective Cover is available for maintenance.
