EHP SERIES
HALF PITCH PIANO TYPE SMT DIP SWITCH

FEATURES

  • Standard 0.05” integrated circuit pitch.
  • Smaller size makes better heat convection during PC board Reflow soldering.
  • Edge actuated type is (Piano type) easy setting on closely racked PCB.
  • Tactile response is performed directly by larger contact pressure to ensure stable contact.
  • All UL 94V-O fire retardant plastics used.
  • Contact wiping on make and break.
  • Gold plated contact to ensure low contact resistance and long mechanical life.

APPLICATIONS

  • Numerical setting for computer terminal equipment
  • Price setting for vending machines
  • Programming for game machines
  • Programming for industrial equipment and measuring instruments
