Dear all,
we have "isSwitchable" in IS and "isNotWired" in IL for a signal, which
might thought to be the same. However, there is different usage for each.
isSwitchable=signal can show different aspects in controlled manner
(mechanically changed or light aspect switched) independent from where
it is controlled.
Beside traffic control signals there for example electrification
signals, which might be switchable in special cases. But then the
steering is from the SCADA of traction power supply system.
1) in Germany switch off (EL1) and switch on (El2) on switchable
insulated overhead section. Then the signal is a combination of both to
be switched from aspect to the other.

see El1/El2
2) in Pontresina, Switzerland: There is a station track which can be
supplied with either traction power supply system. At the mast of the
related exit signals there are additional indicators showing the driver,
which supply system is activated.
isNotWired=signal is not connected to signalbox for control at the outside
This applies typically for a marker board. It is also used in case of
fixed speed indicator (speed is always valid for any route from that
signal).
