- 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. 2. Avoid using coating material containing toluene or xylene. For more information on coating material, please contact us.

Consult with us for availability of TACT Switch TM washing. 2. Prevent flux penetration from the top side of the TACT Switch TM. 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 is stable with normal temperature. 5. Use the flux with a specific gravity of min 0.81. ʢEC-19S-8 by TAMURA Corporation, or equivalents.ʣ Notes Conditions for Auto-dip Available for Snap-in Type and Radial Type ʢExcept SKHJ, SKHL, SKQJ, SKQK, SKEG seriesʣ 1. The above temperature shall be measured on the mounting surface of a PC board. There are cases where the PC board's temperature greatly differs from that of the switch, depending on the material, size, thickness of PC boards and others. The above-stated conditions shall also apply to switch surface temperatures. 2. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended. Note
