Intermittent cockroaches caught off device

Intermittent cockroaches caught off device

Intermittent cockroach trap off a circuit shown in FIG. It is mainly the use of a DC high voltage to kill cockroaches. But because cockroaches are more sensitive to electric fields, can not climb with a high voltage power grid, so take the form of high-voltage circuit intermittently generated.
