<p>The conductor rail (2) is held inside an insulating strip (1) as a hollow profile, and has an angled bottom edge (3) to form the contact strip for the pickup (8). The pickup is inserted through a slot in the supports with the insulation extended into side flanges (6) to protect the entry slot. The bottom edge of the conductor rail (4) hold the insulating flanges against the entry slot so that when a test finger is inserted into the slot it cannot reach the rail.</p> |
