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.
2. Regarding the actuating lever
As an accessory, the standard lever
(Product No. AHR5801) is available sepa-
rately.
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.
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.
5. Regarding changes in operating
characteristics
When selecting the V rotary action switch,
allow
±20% to the rated operating and re-
lease forces.
(Example)
OF: 10.2 g-cm max. specification
10.2
× (100+20%) = 12.24 g-cm
RF: 1.3 g-cm min. specification
1.3 g-cm
× (100–20%) = 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 using V Rotary switches in the
following conditions:
• 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.
