Abstract: An electromechanical switching device, a switching device arrangement and an electric connection module are disclosed. In order to make it easier to connect an electromechanical switching device, a switching device is provided with a base body, and with a connection module that can be connected to the base body and has at least one connection terminal for a main current path of the switching device. In at least one embodiment of the present invention, a modular construction is used instead of the integrated design used in previous switching devices. For that purpose, a number of connection terminals are combined into one or more connection modules for each switching device, and the connection modules can be mounted individually and independently from the base body of the switching device. This makes it possible to pre-wire the connection terminals without the actual switching device. Only afterwards does the base body of the switching device need to be mounted.
