Figure 11 shows the input circuit of U6047B. It has an
integrated pull-up resistance (100 k
(15 PF) and Z-diode (7 V). The circuit reacts to voltages
less than 2 V. The external protective resistance has a
value of 2 k
GND. Contact current, I, is calculated as follows:

The connecting diodes prevent the current flow to the
input of the Z-diodes when the rocker actuated-switch is
in
standby-mode). If necessary, these diodes can be omitted.
