Indicator device

Indicator device for determining the distance between a workpiece set up in a working machine, and a tool set up in a said machine, said device comprising a lower portion (2) with an underside (13) which is adapted to lie against the workpiece, an upper portion (1) with a topside (8) against which the tool is intended to come into contact, resilient means to exert a resilient force on said upper portion, said topside being parallel to the underside (13) of the lower portion and movable towards said underside against the effect of said resilient force, a voltage source (4) and an indicator means (5), the underside (13) and the topside 8 being electrically conductive, insulator means to insulate said underside and topside from each other, and conductive means electrically coupling the indicator means (5) and the voltage source (4) so that the indicator means (5) provides an indication when a circuit (16) between the topside (8) and the underside (13) is closed via the workpiece, the machine, the tool, the voltage source (4) and the indicator means (5).
