<p>The electrical circuit continuity tester uses a commercial battery flashlamp housing enclosing a dry battery (1/9) and an incandescent lamp (1/5). The tester has an additional housing which includes a high rupturing capacity fuse (2/5) and two connection pieces. The connection pieces (2/3 - 2/4) connect the tester to the exterior circuit whose continuity is to be tested. A switch is incorporated in the system to connect the battery, lamp, fuse and contacts in series in one position and battery and lamp in series in other positions.</p> |
