PRECAUTIONS WHEN
USING CADMIUM-FREE
CONTACT TYPE
Models with cadmium-free contacts have
been introduced in order to reduce
environmentally harmful substances. (“F”
is affixed to the end of the part number.)
We ask customers who are currently
using products with cadmium-containing
contacts (no “F” at the end of the part
number) to please make the switch to
models with cadmium-free contacts.
When switching, operating life may differ
depending on the load. Please be sure to
verify this by conducting an evaluation
using actual equipment.
FEATURES
1. Superior anti-weld properties
achieved through forced open contact
construction.
2. Stable contact achieved through
use of AgZnO alloy crossbar contact.
3. Letter display on handle of ON-OFF
type
4. Different handles available for
different applications.

NOTES
Soldering
When using solder to wire this switch, be
careful not to allow solder or flux to enter
the inside of the switch from the small
openings around the terminals as this
can lead to faulty contacting. Bear this in
mind, in particular, for the terminal No.2
on the double throw type.
