CE-Conformity
The products of the Chapter ”PCB Keyswitches” can –
relating to the CE-conformity according to the Low-
Voltage Directive 73/23/EWG – be divided into the
following groups:
All products with an operating voltage U
B
> 50 V
F. ex. Short-Travel Main Switch KN 19, for this product the
Low-Voltage Directive 73/23/EWG applies.
All products with an operating volltage U
B
< 50 V
F. ex. RACON, RF 15, RS 76, for these components no
directive applies.
RG 85 III System
Single parts, accessories and illumination
No directive applies for these products.
EMC-Law
The components of this catalogue are within the meaning
of the law concerning the electromagnetic conformity (=
EMC-Law) ”basic components as, for ex., switches, signal
lamps or like” and, therefore, do not fall within the scope
of the EMC-Law.
Declarations of Conformity
Declarations of conformity for all concerned products are
available and can be delivered upon request. Please
always state the exact order reference of the respective
product.
Marking
The marking will be corresponding to the Low-Voltage
Directive 73/23/EWG resp. the Directive ”CE-Marking
93/68/EWG” either on the packing or on the product itself
or on the shipping documents.

General data
RACON short-travel keyswitches offer an extremely high switching reliability while needing very little space. They can be
arranged as single keys, in rows or key blocks.
When arranged under an overlay, RACON keyswitches should be combined with plungers.
The features at a glance:
• Suitable for the most common soldering methods
- Wave soldering bath for print versions
- Reflow soldering (SMD)
- Manual soldering
• SMD version suitable for processing with an automatic SMD assembly machine
