Abstract

An indicator module in one example has a mounting portion to removably attach the module to another module or base. The indicator module also has a first set of electrodes disposed to be in contact with respective electrodes in the attached module or base. The indicator module further includes an indicator circuit, and a switch module configurable to selectively connect the indicator circuit to one of the electrodes in the indicator module. The indicator module can further include a second set of electrodes connected respectively to the first set of electrodes by conductors. The two sets of electrodes are located at respective ends of the module attach to another module at each end. In visual indicator modules, the conductors can be disposed in a more interior region of the module as compared to the visual indicator elements such as LEDs, which can be distributed near the periphery of the module.
