O Operating range and hysteresis of auto switch
- 36 -
[Example]
Rotary table: 180
o
Switch operating angle: 90
o
When the switch is mounted
at the intermediate position
of the rotation
As shown in the figure shown above, when the magnet rotates in the arrow
direction along with the shaft rotation, the switch turns on when the magnet
passes through the point A, and when it passes through the point B, the switch
turns off. In this case, the ON area is 90
o
, i.e. switch rotation angle is 90
o
.
[Example]
Rotary table: 180

Switch operating angle: 90

When the switch is mounted
at the rotation end
As shown in the left figure above, when the magnet rotates in the arrow
direction, the switch turns on at the position where 45 degrees away from the
the rotation end where the switch is mounted. If the switch is moved by 20
degrees as shown in the right figure above, it will be possible to turn on the
switch at the position where 25 degrees away from the rotation end.
[Example]
Rotary table: 180
o
Switch hysteresis angle: 10
o
As shown in the figure above, when the magnet rotates in the A direction, the
switch turns on at point a. On the contrary, when the magnet rotates in the B
direction, the switch turns off at point b. At this time, the 10 degrees of
hysteresis between point a and b is the hysteresis angle.
