คุณลักษณะ

• Features
• Washable
• Easy pull-up and pull-down (Type A, Type B)
• External parts are not required, saving the number of parts and PC plate area
• The cross pattern is no longer required.
• *There are 3 types of internal circuits in the SA -5000 series.
• A Type Built-in Resistance Network (Housing Color Yellow)
• To use a conventional cord switch in a digital circuit, four external resistors are connected to determine the operating conditions of the IC.
• Hybrid switch with built-in resistance.
• B Type Built-in Pull-Up Resistance and Diode (Housing Color Red)
• C, D Type Diode Built-in (Housing Color Black)
• When multiple chord switches are used as multi-digit chords, signals received on a common line called a common bus line are compared as a method unique to digital circuits.
• To do this, a reverse flow prevention diode must be connected between the output terminal of each switch and the bus line.
• This is a hybrid switch with a built-in diode.
• The diodes of C type and D type are reversed.
