The switching elements, and therefore ratings,
are the same in an isolated position switch as in
a conventional rotary switch. Mechanical life is
also the same.

DESCRIPTION
An isolated position is one which cannot be reached by the normal rotation. An additional action is
required by the operator. It could be either Push-To-Turn, or Pull-To-Turn. After the switch is rotated
to the isolated position, releasing the shaft locks the switch in that position. Push or pull again to
rotate the switch again.
Use isolated positions to protect a switch position from indiscriminate rotation. Such safety positions
might include “calibrate”, “off” and/or “stand-by”.
EXTERNAL DIFFERENCES
The isolated position mechanism increases the
depth of the Series 50 and 51 by 0.217" (5,51
mm). All other dimensions remain unchanged.
In Series 9, 42 and 44, it has the appearance of
an additional deck section without terminals,
located directly behind the detent system.
