電気の特性
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.
