Technical Information (panel / PCB switches)


Dimensions, specifications and data shown in this catalog are subject to change without notice.
Consequently, they are not contractual in any way. Electrical, mechanical and endurance specifications are based upon in-house tests made by APEM.

These tests are conducted using internationally recognized procedures. In the event of a product being used under different conditions, the user must ensure the products 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.


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


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


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


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


The RoHS directive 2011/65/EC of the European parliament and of the Council of June 8, 2011 restricts the use of certain hazardous substances in electrical and electronic equipment:

Mercury (Hg), Cadmium (Cd), Hexavalent Chrome (Cr+6), Polybrominated biphenyls (PBB) and Polybrominated diphenyl ethers (PBDE including decaBDE), 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Switches for printed circuit boards with tin/lead plated terminals (SnPb) have been replaced by components with pure tin plating..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.
