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.  
2. High inrush current resistance is  
ideal for office automation equipment.

Contact gap (more than 3mm)  
The EN60950 (intended for office automation equipment)  
conforms with a 3mm gap.  
When directly opening or closing the primary power supply  
side, a contact gap of at least 3mm is required in order to  
ensure safety.

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.
