Unused Aromat Sealed, Gas Filled K4E-4M-24V-1 24VDC Coil 4PDT 2 Amp Make Before Break Relay. This is a shorting type relay. When initially energized, the moving contact maintains continuity with the normally closed contact before making continuity with the normally open contact. This type of relay is used in circuits where the brief open condition that occurs with a standard type relay might cause noise or other problems. Because the relays are nitrogen filled, the contacts will not oxidize over time.
These relays were used in MCI / Sony JH-24 recorders in the cue switching circuit.
