Abstract
An induction-controlled switch having a vacuum bulb comprising a vacuum chamber and a switch comprising first and second electrodes. The first switch comprising first and second electrodes and further having a first actuator slidably mounted in a first direction and rigidly attached to the first electrode. The first actuator comprising a first armature. A second actuator comprising a second armature. A first control member comprising a first coil configured to simultaneously generate a switching current in the first armature and a current in the second armature via the first coil, so as to separate or bring into contact the first and second electrodes and so as to move the first and second actuators in opposite ways along the first direction.
