Abstract: The disclosure relates to a protective device, for example an overload relay, for attaching the same to a switching device, such as a contactor. The housing wall of the protective device has at least one first and one second recess each on a first side facing the switching device, and on a second side facing away from the switching device, and the recesses are connected to each other such that the switching device is accessible through the recesses for the purpose of connecting a terminal lead.

Abstract: The disclosure relates to an electrical switching device, in particular a thermal relay having at least one contact point in which, in a first position, the contact point is open and, in a second position, the contact point is closed, having a swivelling contact carrier on which the at least one moving contact piece is held and having an actuator for driving the contact carrier. The actuator is a swivel element, which can rotate about a first axis of rotation, said swivel element being made up of two partial elements, which can be slid in mutually opposing directions and are pushed apart by spring force, of which the first partial element is rotatably mounted and the second partial element acts together with the contact carrier at its free end.

Abstract: A pipe tapping valve which can be connected, for example by welding, with a pipe which is to be tapped, and which includes a support stub (4) in which a drill bit (26) is disposed for axial movement, and with which a branch nipple (12) is connected. The pipe tapping valve is configured so that the drilling of the tube can be safely performed with little difficulty, while a seal satisfying the requirements of the particular application is provided both during the drilling and after the drilling has ended. The support stub (4) has a substantially smooth cylindrical inside surface; the drill bit (26) contains at its upper free end an expansion (30) or a sealing ring (54) in contact with the inner surface (34) of the support stub (4), and the drill bit (26) is axially movable by means of a drilling tool (36) attachable to the support stub (4).
