Abstract
A railway signaling relay for use in vital circuits has a high percentage release (ratio of drop away current to pickup current between 70% and 80%) by arrangement of contact springs and their associated pressure and stop plates which provide trapped pressure in the contact springs affording the high percentage release characteristic without modification of the electrical or basic mechanical configuration of the relay and retaining its vital characteristics.
