PRECAUTIONS WHEN
USING CADMIUM-FREE
CONTACT TYPE
12 dia.
1. High performance and excellent
characteristics.
An AH7 snap action switch is used in the
switch body and since the installation
frame is made of molded plastic,
dimensional accuracy is now on a new
level.
2.Two series: push type and lock type
Lock type also available that locks when
rotated.
3. Six push-button colors
You can use colors in accordance with
sequence functions.
4.The switch body uses an AH7 snap
action switch (O.F. 3.92 N max. type).
Also, if dirt and water resistant
properties are required of the internal
switch, a V type turquoise switch
(sealed type snap action switch) can
be built in. Please inquire.
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.
