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.

NOTES
1. Switch mounting
Avoid touching the switch with soldering
iron.
3. Resistance to chemicals
To clean the switch unit, use a neutral
detergent diluted with water.
Do not use acidic or alkaline solvents as
they may damage the switch.
Furthermore, be careful not to get any of
the detergent solution inside of the switch
while cleaning it.
Mount the switch with the hole cutting
dimensions shown in the dimensions.
Contact us if you are considering using a
panel of other than the recommended
size and shape.
Soldering position
When wrapping or soldering a wire
around a terminal, do so in the shaded
area indicated in the diagram at left.
2. Regarding fastening lead wires to
terminals
Contact terminal and ground terminal
1) When connecting the tab terminals,
use a .250 Quick-connect and insert the
terminals straight in.
If they are skewed, the terminals will
require excessive insertion force.
In addition, there is some variation in the
insertion force required for different
receptacles from different manufacturers,
so confirm how much force is needed
under actual conditions.
Do not solder wires onto tab terminals.
2) With manual soldering: Complete the
soldering connection work within 3
seconds with the tip of the soldering iron
(60W soldering iron) at a temperature of
420°C or lower, and take care not to
apply any force to the terminal area.
4. Environment
Refer to the diagram above, “soldering
position,” for details on the position where
a wire should be soldered to a terminal.
When soldering PC board terminals,
keep soldering time to within 5 s at 270°C
soldering bath or within 3 s at 350°C
soldering bath.
3) The terminals should be connected in
such a way that they are not under
constant stress from the connecting
wires.
Avoid using and storing these switches in
a location where they will be exposed to
corrosive gases, silicon, or high dust
levels, all of which can have an adverse
effect on the contacts.
5.Take care not to drop the product as
it may impair perfomance.
4) Terminal material is copper alloy which
may discolor due to finger’s oil or after a
long time. But that discoloration does not
effect actual performance.
