The utility model discloses a relay test device, include: power, first switch, test relay, test pilot lamp and be used for the installation to be surveyed the relay base of relay, power, first switch and relay base establish ties in proper order, test relay establishes ties with the test pilot lamp, the series branch of test relay and test pilot lamp is parallelly connected with relay base, during first switch closure, is surveyed relay coil and test relay coil and got electricly, make the coil pilot lamp of being surveyed the relay give out light, give off light with the test pilot lamp, it is when coil pilot lamp and the luminous unanimity of test pilot lamp, normal by the test relay actuation, otherwise, it is unusual by the test relay actuation. This relay test device simple structure, easily operation, test effectiveness is directly perceived, and convenient to use person observes the actuation state of being surveyed the relay.
