tance (20 kΩ), RF capacitor (15 pF) and Z-diode (7V). It reacts to voltages greater than 2V. The
external protective resistor has a value of 20 kΩ and the push-button switch, S, is connected to
the battery as shown in the diagram.
Contact current, I, is calculated as follows:
It can be increased by connecting a 5.6 kΩ resistor from the push-button switch to ground as
shown in
Figure 3-4.
