An impulse mercury relay with magnetic interlock switch is provided comprising a first electrode member containing a body of a liquid conductor therein, a second electrode member received and secured inthe first electrode member, and a displacement plunger movable in the first electrode member to cause contact between the liquid conductor and second electrode member. A magnet device is movable with the displacement plunger, and a magnetically-actuable switch externally disposed of the first electrode member is actuated by the magnet when moved with the displacement plunger. A holding device is also provided to magnetically hold the displacement plunger at the desired position when the coil device is deenergized.
