Abstract
The invention concerns switchable serial terminals with a switching lever gripping component consisting of an insulating material. It is suggested that one provide the gripping component with two visual surfaces--of which in each of the two switching positions of the switching lever and in an alternating manner--one visual surface is turned toward the viewing direction of the operator and, in the same switching position, the other visual surface is turned away from the viewing direction of the operator.
Claims5
In a rail mounted terminal block having a lever switch element for disconnecting the through connection of a circuit, the lever being rotatable about a lever axis and having a handle made of insulating material which is movable from a first switching position on one side of a plane of the terminal block to a second switching position on the other side of the plane of the terminal block, the plane being defined by the lever axis and being generally parallel with respect to a view direction of an operator looking onto the terminal block, wherein the improvement comprises the handle having two marking areas defining visible surfaces, each marking area being adapted to receive a marking, one of said marking areas being visible when the lever is in its first switching position and the other marking area being visible when the lever is in its second switching position.
