Figure 30. Switch interface. This circuit can be used to interface a change-over switch to the CyberAmp.
Such switches would typically be used to activate one of the digital inputs or a counter input in the data
acquisition system. Capacitor C2 eliminates false triggering due to contact bounce. Resistor R1 limits the
transient current drawn from the 5.000 V supply. Capacitor C1 stores the charge required to rapidly step C2 to
at least 4.55 V.
