Features
Soft feeling type with metal contacts achieving low contact
resistance.
Supplied with radial taping.
Round terminals are most suitable for radial auto-insertion/mounting
onto the PC board. (reduces switch rise during mounting and also
reduces cutter wear outs caused by the insert machine.)
Better solderability thanks to no rupture plane of the terminal.
Applications
For car AV equipment and car navigation systems
For various operation in audio equipment, communication devices,
measuring instruments, in-car components, etc.

Note
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.

Notes
1. Consult with us for TACT SwitchTMwashing conditions.
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 returns to normal temperature.
5. Use the flux with a specific gravity of min 0.81.
