FEATURES  
1. Power switches with an electromag-  
netic reset function which meet the  
need for energy savings in equipment  
and for safety.  
Applications for these switches include  
promoting energy savings in equipment  
(by reducing power consumption when  
OA equipment is in standby mode, for  
example), preventing fires caused by  
overheating of a heater inside equipment,  
preventing electrical leaks, and automati-  
cally turning off the power if the unit tips  
over or is shaken.These switches feature  
a built-in electromagnetic reset function  
The switch uses our own proprietary  
mechanism that provides an excellent  
ability to withstand inrush current is  
employed.  
Inrush current rating (IEC65) : 160A (nor-  
mally 16A at 125V AC), 10,000 times  
6. Approved under major international  
safety standards.

3. CT terminals adopted for coil termi-  
nals  
These switches can be used with AMP's  
CT connectors, which are widely used for  
wiring connections in OA equipment,  
UL, cUL, TÜV and SEMKO approved.  
OPERATING PRINCIPLE  
• Manual operation is a repetition of (A) and (B) .  
This operation is independent of the electromagnetic reset function.  
• The reset mechanism operates only when an electromagnetic reset has occurred. (C)

ommended size and shape.  
Remarks: 1. The external dimensions and mounting dimensions for the single pole, single throw  
type and the single pole, double throw type are the same as those for the double pole,  
single throw type indicated above.  
2. The figures show the double pole, single throw (ON-OFF) type as an example.  
The contact terminals are 1, 2, 3, and 4.  
In the case of the single pole, single throw (ON-OFF) type, the contact terminals are 1  
and 2.  
In the case of the single pole, double throw (ON-ON) type, the contact terminals are  
1, 2, and 4.  
There are no other terminals.  
Refer to the internal wiring diagram.  
3. The coil is a polarized coil; coil terminal 5 is positive and coil terminal 6 is negative.

NOTES  
1. Operating voltage application time  
If the rated voltage is applied to the coil  
for more than 10 seconds or the maxi-  
mum voltage is applied for more than 1  
second, coil performance may deterio-  
rate.  
(3) Use a receptacle that is compliant  
with JIS C 2809.  
10.This product is not hermetically  
sealed, so its performance could dete-  
riorate under certain ambient condi-  
tions. Avoid using and storing these  
switches in a location where they will  
be exposed to corrosive gases, sili-  
con, or high dust levels, all of which  
can have an adverse effect on the con-  
tacts. In addition, because these  
switches contain permanent magnets,  
avoid using and storing these  
In addition, there is some deviation  
regarding the insertion force depending  
on the model used from different manu-  
facturers, so the insertion force should be  
checked under realistic conditions.  
(4) Use AMP's CT connector for the coil  
terminals.  
6. Because special receptacle termi-  
nals are used for the contact terminals  
and the common terminals, do not  
attempt to solder them. Doing so  
could melt plastic components and  
otherwise harm the performance of  
the switch  
7.The terminals should be connected  
in such a way that they are not under  
constant stress from the connecting  
wires.  
8.Take care not to drop the product as  
it may impair performance.  
2.The shape of the mounting panel  
should be as recommended in the  
dimensions diagram.  
Contact us if you are considering using a  
panel of other than the recommended  
size and shape.  
3.The mounting panel should be made  
of SPCC. If a different material is used,  
its adhesion to the switch unit may be  
not be as strong. Check this on site if  
necessary.  
4. Note that the actuator could pop out  
of the switch housing if 19.6N (2kgf) or  
more of force is applied to the side of  
the actuator.  
switches in a location where metallic  
dust, etc., is present.  
11.When these switches are used with  
weak currents of 500mA or less, a  
layer of material on the surface of the  
contacts may cause contact instabil-  
ity. Check and evaluate this possibility  
before using these switches under  
such conditions.  
12. When using an ON-OFF type  
switch with no (|O) indication on the  
actuator, the "OFF" position should be  
indicated on the set in which the  
switch is installed.  
5.  
(1) When connecting the tab terminals,  
use a .250 receptacle and insert the ter-  
minals straight in.  
9. Resistance to chemicals  
To clean the switch unit, use a neutral  
detergent diluted with water.  
If you insert them at an angle, the termi-  
nals could catch on the opening and will  
require greater insertion force.  
(2) The coil terminals have specific polar-  
ities. Make sure you connect them cor-  
rectly.  
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.  
13.To assure reliability, check the  
switch under actual loading condi-  
tions. Avoid any situation that may  
adversely affect switching perfor-  
mance.  
COIL TERMINAL CONNECTOR  
Because CT terminals are used for the  
coil terminals, AMP's CT connector can  
be used.
