Sneak circuit path within a DPDT relay

Sneak circuit path within a DPDT relay

A failed resistor in an electronic circuit was found to have been subjected to an overvoltage condition. One side of the resistor was connected to a dual-coil DPDT latching relay, and the other side to ground. The cause of this failure was found to be due to a threefold problem: 1. A test set that,...

Zusammenfassung:A failed resistor in an electronic circuit was found to have been subjected to an overvoltage condition. One side of the resistor was connected to a dual-coil DPDT latching relay, and the other side to ground. The cause of this failure was found to be due to a threefold problem: 1. A test set that, when powered on, would send simultaneous commands to both relay coils. 2. A sneak path through the relay when both relay coils were simultaneously energized. 3. A design that did not consider this sneak path.< >
