Abstract

PURPOSE: To obtain a simple, inexpensive and highly reliable impact protector by an arrangement wherein the circuit is interrupted by detecting a leakage current. CONSTITUTION: Special sensor wires W, in the form of at least one noninsulated wire, are arranged at various parts of a small apparatus and a voltage is supplied thereto through diode rectifiers D1 , D2 and a relay R. When the sensor wire W touches a conductive liquid, a leakage current flows from the sensor wire W through a shortest path to inner and outer grounding points of the apparatus. Consequently, the relay R is excited and power supply to a load is interrupted. At the same time, a circuit is formed through diodes D3, D4 and the relay R is latched.
