Modular indicator

An indicator module, comprising:

• a first support surface;
• a first plurality of electrodes disposed on the first support surface;
• a second support surface spaced apart from the first support surface along a longitudinal direction, the first and second support surface facing substantially away from each other along the longitudinal direction;
• a second plurality of electrodes disposed on the second support surface;
• a plurality of conductors elongated substantially in the longitudinal direction, each of the first plurality of electrodes being electrically connected to the a respective one of the second plurality of electrodes via a respective one of the plurality of conductors;
• a spacer disposed between the first and second support surfaces, accommodating the plurality of conductors passing through the spacer, and spacing the plurality of conductors apart from each other;
• and
• an indicator circuit electrically connected to one or more of the plurality of conductors and adapted to generate a human perceptible signal when the indicator circuit receives electrical power from the one or more of the plurality of the conductors.

An indicator assembly, comprising:

• a first and second indicator modules, each of which comprising:
• a body portion having a first mounting portion and a second mounting portion spaced apart from the first mounting portion along a longitudinal axis;
• a first support surface proximal to the first mounting portion of the body portion;
• a first plurality of electrodes disposed on the first support surface, each of the first electrodes comprises a flexible portion having a sloped section forming an oblique angle with the first support surface and having a lower end portion and an upper end portion disposed farther from the first support surface than the lower end portion;
• a second support surface proximal to the second mounting portion of the body portion, the first and second support surface facing substantially away from each other along the longitudinal axis;
• a second plurality of electrodes disposed on the second support surface;
• a plurality of conductors elongated substantially in the longitudinal direction, each of the first plurality of electrodes being electrically connected to the a respective one of the second plurality of electrodes via a respective one of the plurality of conductors;
• and
• an indicator circuit electrically connected to one or more of the plurality of conductors and adapted to generate a human perceptible signal when the indicator circuit receives electrical power from the one or more of the plurality of the conductors;
• the second mounting portion of the first indicator module and first mounting portion of the second indicator module being adapted to engage each other to form a mating attachment between the first and second indicator modules,
• each of the second plurality of electrodes of the first indicator module and a corresponding one of the first plurality of electrodes of the second indicator module are adapted to form compressive contact with each other when the second mounting portion of the first indicator module and the first mounting portion of the second indicator module are in a mating attachment to each other.
