Abstract of the Invention An improved spring biased reciprocable latch-reset member is provided for a relay of the type including an armature mounted on a support block for pivotal movement about an axis, a coil for displacing the armature from a first position to a second position when the coil is ener- gized, a spring biasing the armature from the second position to the first position when the coil is de-energized, and an electrical contact controlled by the position of the armature. The latch-reset member is operable in response to displace- ment of the armature to the second position by energization of the coil to hold the armature in the second position, and is displaceable thereafter to release the armature for movement back to the first position by the armature biasing spring. The improvement in the latch-reset member provides for a component displaceable therewith to engage and dis- place the armature from the first to the second position thereof independent of energization of the coil, thus to provide for testing a circuit with which the relay is associated.
