Abstract
A magnetic safety closure for a protection device that is movable with respect to a fixed part includes a housing that is attachable to the protection device and includes a handle for opening and closing the protection device. The housing includes a sensor housing that is attachable to the fixed part and provided with a sensor for determining whether the protection device is closed or open. The housing attachable to the protection device has an initiating device for the sensor and is opposite the sensor when the protection device is closed. The housing and the sensor housing share a magnet arrangement having at least one holding magnet and an associated pole plate. The handle is a two armed lever pivotably mounted on the housing, with arm of the lever facing the sensor housing with its free end disconnecting the holding magnet from its associated pole plate when the handle is pivoted out in order to open the protection device.
