The AZ957 is a single-pole double-throw switch produced by ZETTLER electronics GmbH. The operating voltage is 60 VDC or 125 VAC, the maximum switching current is 1 A, the maximum switching power is 30 W or 62.5 VA, the contact material is silver palladium gold alloy, and the rated load is 1.0 A 30 VDC resistive load, 0.3 A 60 VDC resistive load, and 0.5 A 125 V AC resistive load. The life span is 10 million mechanical operations, 100,000 electrical operations.
The AZ957 is a subminiature SPDT (1 Form C) PC board relay designed for high‑density packaging. It features epoxy sealing for wave soldering, high sensitivity (150 mW nominal, 96 mW pickup), and meets FCC lightning surge and dielectric standards.
The relay offers a standard coil (200 mW) and a sensitive coil (150 mW) with various voltage options, a maximum switched power of 30 W (62.5 VA), and can operate from –40 °C to 70 °C. Ordering data, mechanical layout, and wiring diagrams are provided for easy integration.
