The SWT8 Series switches measure 6.2 x 6.2mm with a 2.4mm and 2.8mm square stem.
The switch includes an expanded number of actuation forces ranging from 1 to 5N.
Available configurations for the SWT8 Series include: SWT8-R side actuation through-hole; SWT8-V top actuation through-hole; and SWT8-M top actuation surface mount.
Square and round caps are available for the 2.4mm square stem.
The caps, with SWT8-C part number designation, are offered in a variety of colours.
Specific applications for the tactile switches include: (appliances) dishwashers, vacuum cleaners, paper shredders, and coffee makers; (medical devices) digital thermometers, blood pressure measurement, and medication dispensing machines; (personal electronics) LCD monitors, remote controls, and set-top boxes; cameras, MP3 players, video keyboards; and (automotive) radios, steering wheel controls and CD players.
All devices in the tactile switch product family are RoHS-compliant, and meet or exceed competitor performance specifications.
BI Technologies will also produce devices beyond standard specifications and dimensions to meet customer requirements.
Typical pricing for the tactile switch products is US $0.06 to $0.15 depending on quantity, with lead times from stock to 4 weeks.
