Isolating clips for fischertechnik electronic modules

For connecting the traditional fischertechnik electronics modules, small red clips are used with which the power supply voltage can be looped through via conductive metal strips on the sides of the modules. But when modules are connected in several rows, clips are not needed for all connections. With this insulating clip, superfluous (or unwanted) connections between modules can be neatly covered. Of course, these isolating clips are also useful for isolating several rows of modules with separate power supplies.
