Abstract: The invention relates to a connection element for the electrical connection of a signal device to a functional module adjacent to the connection element, such as a lighting module for signaling one or more different operating states of a technical device such as a machine, a plant, a vehicle or the like, or a radio module for producing a radio connection of the signal device, wherein the connection element for the electrical connection of the functional module has at least one electrical contact surface of an electric conductor. The connection element is distinguished by the fact that the electric conductor having the contact surface extends as far as a cable connecting clamp of the connection element for the connection to at least one cable core of an electric cable.

Abstract: An optical signaling device, in particular a signal pillar (1) of modular construction or similar with at least one first exchangeable light module (3) comprising at least one light element (10) is proposed for optical indication of one or more different operating states of a technical device (2) such as a machine, a plant, a vehicle or similar, wherein the first light module (3) comprises at least one first circuit board (11) oriented essentially in direction of a longitudinal axis (8) of the signaling device with the at least one first light element (10) and electrical components, wherein at least one contact (32) is provided between at least one first detachably contactable electrical contact surface (19) and a second electrical contact surface (18) of an adjacently arranged module (3, 4, 5, 6, 7) configured as a second light module (3) and/or as a holding module (5) and/or as a base module (6) for holding and connecting the signaling device at an operating position, wherein the adjacently arranged module
