During the product revision a new shaft retaining system was presented for base mounting switches with metal shaft extension. The new version with shaft retaining screw was introduced in addition to the previous mounting forms with shaft retaining bush. The adjustment of the shaft length, which is done once during the assembly process is simplified as no additional tool (wrench) is required. Another advantage is the reduced height of the switch body which allows the switch to be installed in enclosures with a smaller depth. The reduced height of the switch body can result in a different shaft length, please see chart below. the stability remains the same - for H400 up to mounting depth of 420mm.
