Abstract
A transformer includes a transformer housing, a stationary contact, a load break rotary switch—and a magnetically sensitive indicator component. The load break rotary switch comprises a shaft, comprising a shaft portion which is disposed in an inner housing area and a shaft contact attached to the shaft portion. The load break rotary switch comprises a lever connected to the shaft portion with respect to a rotary axis in a rotationally fixed manner, wherein the lever comprises a lever portion having a radial distance from the rotary axis. The lever portion comprises a lever magnet. A 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. Thus, an operator can ensure that the shaft contact is disconnected from the stationary contact before performing a maintenance work.
