General Notes
The series 99contains indicators and illuminated pus hbuttons with
maintained and momentary action with one or two contacts which
may be either normally open or normally closed o r a combination of
the two. The illuminated pushbuttons are equippedwith the low- level
switching system.
The series 99 PCB keylock switch with a spacing of 19.05 mm completes the existing range of indicators and illuminated pushbuttons.
The PCB keylock switch is available with two and three positions,
with maintained action, and with either o n e or two normally opencontacts as well as with one normally open and one normally closed one.
Mounting
The illuminated pushbuttons of series 99c an besolderedto a printed
circuit board. The contact layout conforms to the module of 2.54 mm
(1/10“). A centering pin ensures dimens ionally exact mounting in
rows or blocks.
With an M 1.2 screw t h e pushbuttons can also be fixed to a printed
circuit board. (This screw must be ordered separately.) The pushbuttons can be joined together easily with a coupling piece to form rows
or blocks.
The layout of the PCB keylock switchconforms to t he module of 2.54
mm (1/10“).
Two centering pins ensure a dimensionally exact mounting. The contact layout corresponds to that of series 99 switches.
Rules for cleaning soldered PC boards
In many cases the boards are cleaned following mechanical soldering. In this case itis essential to prevent thecleaning fluid containing
dirt, grease and flux from enter ing the switch.
ordered by quoting no. 31-989.300.
Two keys are supplied with each keylock switch.
Spare keys for standard DOM locks may be ordered by quoting no.

Lenses
The lens consists of a bezel, a marking plate and a transparent lens
plate, which may be either flat or concave.
Marking
For engraving, hot stamping and film inserts, see under “Markings”
on page 546.
Illumination
Illumination of the different coloured lenses is by lamps bipin T 1 longlife (6-36 V) or LED bipin T 1.
Position indication
When a switch with maintained action is actuated, the lens remains
in the depressed position mechanically. The state of t h e switch is apparent at all times from the position of the lens.
