1. A vacuum bulb switch (1) with inductive control, comprising:
a vacuum chamber (110);
a first switch (111) having first and second electrodes (1113, 1111) housed in the vacuum chamber and capable of being selectively brought into contact with or separated from each other, the first switch (111) further comprising a first actuator (12) mounted so as to slide in a first orientation (A) and integral with the first electrode (1113), the first actuator comprising a first armature (122); characterized in that it further comprises:
a second actuator (22) slidably mounted in the first orientation, the second actuator (22) having a second armature (222);
a first control-element having at least a first coil (131) positioned between the first armature (122) and the second armature (222) and configured to simultaneously generate a switching current in the first armature and a current in the second armature through said first coil (131), so as to separate or to put into contact the first and second electrodes (1113, 1111) and so as to move the first and second actuators in opposite directions along the first orientation.
