TACT Switch
6.45mm Diameter Low contact Resistance with Round Terminals (Radial type)
SKPL Series
Soft feeling, low contact resistance metal contacts and round terminals with excellent PC
board mouting performance.
Features
Detector
Push
●
Soft feeling type with metal contacts achieving low contact
resistance.
●
●
Supplied with radial taping.
Slide
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.

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 SwitchTM washing conditions.
2. Prevent flux penetration from the top side of the TACT SwitchTM.
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.
