Transformer comprising a load break rotary switch

A transformer, comprising:

• a transformer housing, comprising a transformer housing wall separating an inner housing area from an outer housing area;
• a stationary contact disposed stationary relative to the housing;
• a load break rotary switch comprising
• a shaft, comprising a shaft portion which is disposed in the inner housing area and a shaft contact attached to the shaft portion, wherein the shaft is supported with respect to the transformer housing wall rotatably about a rotary axis (R) between a first position in which the shaft contact is electrically connected to the stationary contact and a second position in which the shaft contact is electrically not connected to the stationary contact;
• and
• a lever connected to the shaft portion with respect to the rotary axis (R) in a rotationally fixed manner, wherein the lever is an integral part of the shaft portion or a separate part, attached to the shaft portion, wherein the lever comprises a lever portion having a radial distance (d) from the rotary axis (R), wherein the lever portion comprises a lever magnet, wherein the lever is disposed entirely within the inner housing area;
• and
• a magnetically sensitive indicator component attached to the transformer housing wall, wherein the magnetically sensitive indicator component is placeable selectively into a first state in which the magnetically sensitive indicator component is indicative of the first state and into a second state in which the magnetically sensitive indicator component is indicative of the second state,
• wherein the magnetically sensitive indicator component is switched from its first state into its second state by the lever magnet when the shaft is rotated from the first position to the second position or vice versa.
