Overview
Two-way switches are used in control cabinets and distribution
boards for switching small loads on/off or over.
Group switches with center position permit the positions
open/stop/closed, for example to control anti-clockwise rotation
-
Off - clockwise rotation.
Control switches in a range of contact versions have an integral
control lamp for the ON setting.
The auxiliary switch (AS) signals the contact position of the switch.
It has the same design as the auxiliary switch used for the miniature
circuit breakers
(
see Chapter "Miniature Circuit Breakers")
.
■
Benefits
•
The control switches can be bus-mounted with each other or with
5
TE4 8 pushbuttons, 5TE5 8 light indicators or 5TT4 1 remote
control switches and 5TT4 2 switching relays. This saves time
and space.
•
For busbars, see page
see page 7/22 ff
.
•
The handle locking device prevents undesired manual on and
off switching. This increases safe operation.
•
The handle locking device is a universal accessory for all
switches and miniature circuit breakers. This simplifies logistics.
