Miniature, Space-Saving Tactile Switch Provides
Long Service Life and Easy Mounting
■Extended mechanical/electrical service life:
10 x 106 operations for 12 x 12 mm type and
1 x 106 operations for the 6 x 6 mm type
■Ideal for applications such as audio, office
and communications equipment, measuring
instruments, TVs , VCRs , etc.
■Taped radial type, vertical type, high force type,
and gold-plated contact type are available as
series versions
■Flux-tight base structure allows automatic
soldering of the tactile switches onto a PC board
