Features:

• Tactile response is performed directly by larger contact pressure to ensure very stable contact.
  
• All plastics are UL 94V-0 grade fire retardant.
  
• Bottom epoxy sealed standard to ensure free of flux immersion during wave soldering.
• Contact wiping on make and break.
• Gold plated contacts to ensure low contact resistance and long mechanical life.
• Ideal for data processing, communications, remote controls and burglar alarm system use, where manual programming is required.
