 SPECIFICATIONS 
Dimensions, specifications and data shown in this catalogue are subject to change without notice. Consequently, they are not contractual in any case. Electrical, mechanical and endurance specifications are based upon in-house tests made by APEM. These tests are conducted using internationally recognised procedures. In the event of a product being used under different conditions, the user must ensure the product’s suitability for use under those conditions. Incorrect storage, handling, operation or application of the product may result in damage to the product or equipment. 
The negative value indicated under “Operating temperature” is given for normal usage conditions (products free of moisture, which could generate frost or ice and block the mechanism). 
The specifications give the technical performances of the switches. If the equipment on which our products are mounted is submitted to safety standards, the customer should select approved models or models conforming to the standards (marked CE only). Consult factory for details of models that can be marked CE.

DRAWINGS 
Products are shown with their standard actuator (for other actuators, see options). 
Scale : drawings in this catalogue are to different scales : ask for a data sheet if you need other dimensions for a specific part number.

TOLERANCES 
Unless otherwise specified, the general tolerance for dimensions in this catalogue is ± 0,3 (.012). 
Overall dimension tolerance is ± 0,5 (.020). Ask for a data sheet for further information.

PART NUMBERS 
To order a switch model, every option has to be specified. However, for the S series toggle switches and 18000 series pushbutton switches, we continue to accept former part numbers using default options. If the actuator is not specified, we will supply lever or plunger -13.

SOLDERING CONDITIONS 
Hand soldering with iron : 300°C, 3 seconds max.

SEALING OF TERMINALS 
Due to the new generations of active flux, epoxy sealing of terminals is preferred, to prevent any risk of switch 
contamination.

ROHS COMPLIANCE 
The RoHS directive 2002/95/EC of the European parliament and of the Council of 27 January 2003 restricts the use of certain harzardous substances in electrical and electronic equipment: Mercury (Hg), Cadmium (Cd), Hexavalent Chrome (Cr+6), Polybrominated biphenyls (PBB) and Polybrominated diphenyl ethers (PBDE), Lead (Pb). 
  • Standard products manufactured by APEM are already and will remain in compliance with the restriction of the marketing and use of the above mentioned substances imposed by such directive.
  • Switches for printed circuit boards with tin/lead plated terminals (SnPb) have been replaced by components with pure tin plating.
  • For specific options using LED illumination, wires are soldered with lead-free solder.

There is no change of part number for RoHS compliant products. 
Some specific products or options can still be supplied in non-RoHS version with customer’s agreement.

Contacts and ratings

Contact materials

Several contact technologies are available depending on models : 

For miniature switches 
A End contacts : silver. 
Center contacts and terminals : brass, silver plated. 
For high ratings at 125VAC - 250VAC or over 0,1A 30VDC (levels III and IV).
AD End contacts : silver with gold plating over nickel barrier. 
Center contacts and terminals : brass, gold plated. 
For low level applications (levels I and II). 
Can be used for high ratings (level IV), 
the gold layer being considered only as a protection against oxidation during storage.
CD Contacts and terminals : brass with gold plating over nickel barrier.
or LD For low level applications up to 20mA 20VDC or 80mA 5VDC (levels I and II).
X780 Silver rivet, gold plated (11000 and 12000 series).

For industrial switches 
A End contacts : silver rivet or silver inlay. 
If not specified in model number, the contact material is indicated in the specifications of each series.
C Silver plated copper or brass.

Silver cadmium oxide contacts (S) which used to be available on the 4000 - 600H - 600NH and 2600 series, are 
discontinued and will be replaced by silver tin oxyde contacts before 2005.
