Alps Electric Switch SKPL Series User Manual

TM  
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.
