NOTES  
1. Method of attaching actuating lever  
Insert tha lever in the rotating spindle,  
then place the retainer over the spindle to  
lock the lever in place as shown in Fig. 1.  
Be sure that the retainer has snapped  
over the lugs on the rotating spindle, with  
the lugs entering fully into the holes in the  
retainer.  
4. Regarding switch mounting  
Mount the switch to a smooth surface us-  
ing M3 screws.Tighten the screw with 3 to  
5 kg-cm torque. To prevent loosening of  
the mounting screws, it is recommended  
that spring washers be used in combina-  
tion with adhesive material for locking the  
screws.  
In the mounted condition, the insulating  
distance between each terminal and  
ground should be checked for assurance  
of proper distance.

Hole (2 places)  
5. Regarding changes in operating  
characteristics  
Actuating lever  
When selecting theV rotary action switch,  
allow 20% to the rated operating and re-  
lease forces.  
Rotating spindle  
(Example)  
Lug section (2 places)  
OF: 10.2 g-cm max. specication  
10.2 × (100+20%) = 12.24 g-cm  
RF: 1.3 g-cm min. specication  
1.3 g-cm × (10020%) = 1.04 g-cm  
6. Adjustment of the operating object  
The positioning of the operating object  
should be such that when direct force is  
not applied to the actuator, the actuator is  
in its free position. The operating object  
should apply force in the operating direc-  
tion. The standard value of overtravel to  
be used should be set within the range of  
70% to 100% of the rated O.T. value. Fur-  
thermore, if the operating position limit is  
exceeded, the electrical and mechanical  
life of the switch will be shortened.  
7. Avoid usingV Rotary switches in the  
following conditions:  
2. Regarding the actuating lever

(Product No. AHR5801) is available sepa-  
rately.

At time of mounting,

3. Cautions regarding design of actuat-  
ing lever  
The dimensions of the lever at the mount-  
ing section are as shown in Fig. 2. These  
dimensions should be used in the design  
of an alternate actuating lever. The mate-  
rial can be stainless steel wire or piano  
wire. The standard lever length is 50 mm  
1.969 inch. A lever in excess of this length  
would have a weight which could cause  
erroneous operation.  
Where the ambient temperature ex-  
ceeds the range of 25°C to +65°C 13°F  
to +149°F.  
Where the relative humidity exceeds  
85%.  
Where the permissible operating speed  
of 1 to 100°/sec. is exceed.  
Where the operating speed of 240 cpm.  
is exceeded.  
Where the lever length of 50mm  
1.969inch is exceeded.
