Description
General Notes
The indicators, illuminated pushbuttons, selector switches, keylock
switches and emergency stop switches with spray-water protection at
the front (IP 65) are modular and consist of an actuator and switching
element. In addition to the standard switching elements (gold-plated
silver contact with universal soldering or plug-in terminals), forced-
opening, slow-make switching elements with gold or silver contacts
and soldering or plug-in terminals are available. They can be supplied
with screw terminals and silver contacts too. The front dimensions of
the units in this series are 24 x 24 mm, 24 mm dia., 18 x 24 mm, 18
x 18 mm or 18 mm dia. For flush mounting the dimensions
25 mm dia., 24 x 30 mm and 24 x 24 mm can be supplied.
Mounting
All switch actuators are mounted from the front by pushing them
through the mounting hole in the front panel. They are then fixed from
the back with a fixing nut and the mounting tool typ no. 01-907. Max.
tightening torque 50 Ncm. For mounting dimensions and grid size see
as of page 145.
The preassembled switching element with the connecting wires in a
single plane can be clipped on afterwards. For block or series mount-
ing aids are available.
For switching elements with 2.8 mm plug-in terminals, we offer plug-
in bases, which when soldered to a PCB enable a plug-in connection
to the button. All actuators are provided with an anti-rotation device.
Lenses
The flat or concave lenses are available in various colours and a
transparent or translucent version. The lens surface is non-reflecting
(matt). Lenses 19.7 mm dia. can be supplied also in aluminium.
Marking
For engraving, hot stamping and film inserts, see page 153 under
“Marking”.
Illumination
The midget-grooved T 1 3/4 incandescent lamp (6-60 V, 1.2 W) en-
sures perfect illumination of the lenses, which are supplied in various
colours.
Midget-grooved T 1 3/4 Multi-LED (6, 12, 24, 48 V) are also available
in white, red, yellow and green.
For supply voltages above 60 V, it is necessary to use a voltage re-
duction element (external series resistor, capacitor or transformer).
Do not solder the terminals directly, bacause of the high surface tem-
perature.
Position indication
When the switch with maintained action is actuated, the lens snaps
into place mechanically. The position of contacts can always be de-
termined by the position of the lens.
Keylock switch
Standard lock (index D)
1 standard number 311. If the lock number is not specified, we will
supply no. 311. An additional 134 special locks (index X) are availa-
ble on request. Master keys for locks no. 311 - 445 may be ordered
by quoting no. 31-989.300.
Two keys are supplied with each keylock switch.
Spare keys for DOM standard locks may be ordered by quoting no.
31-989 (please state the lock number).

Kaba safety lock. Standard lock number is 1001. Locks with other
numbers are available on request.
Spare keys for KABA locks may be ordered under no. 14-987
(please state the lock number).
