1. Do not washing the TACT Switch™.
2. Prevent flux penetration from the top side of the TACT switch™.
3. Switch terminals and a PC board should not be coated with flux prior to soldering.
4. The second soldering should be done after the switch returns to normal temperature.
5. Use the flux with a specific gravity of at least 0.81.
(EC-19s-8 by TAMURA Corporation, or their equivalents.)
Notes are common to this series/models.
1. This site catalog shows only outline specifications. When using the products, please obtain formal
specifications for supply.
2. When the switch is used in an environment subject to high humidity or condensation, make sure the
terminals are coated thoroughly to prevent current leakage between terminals.
3. Avoid using coating material coating toluene or xylene. For more information on coating material,
please contact us.
4. Switch terminals must be coated thoroughly until the terminals are fully covered.
5. For more information on coating material, please contact us.
6. Please use 1.6mm thick PC boards.
7. Please place purchase orders for taping products per minimum order unit (1 box or a case).
8. Please contact us for automotive use products.
