Telephone Extension Relay

Abstract

The relay as submitted is not satisfactory for installation in ships service telephone systems because of its failure to comply with the requirements of the specifications with respect to shock integrity. This relay, if modified to incorporate a "Burgess Micro Switch" in place of the "Burgess Vacuum Contactor", would be satisfactory for the Naval Service. That the relay, as submitted, be not approved for the Naval service because of its failure under shock. That the relay, if modified by the manufacturer to incorporate a "Burgess Micro Switch" with a 1 manufactured condenser in series with a 0.5 ohm resistor shunted across with switch contacts, be approved for installation in ships service telephone systems. It is recommended that all modified parts be nickel plated for protection against corrosion.
