- and
- a shaft disposed within the internal bore, the shaft having a second surface that is matable with the first surface in a mating orientation, wherein upon rotation of the first surface relative to the second surface in the mating orientation, the series of indentations provide a tactile and/or auditory signal, wherein the first housing is made of a first material and the shaft is made of a second material, the first material being weaker than the second material such that the first surface is configured to be damaged prior to the second surface during rotation of the first surface relative to the second surface in the mating orientation.
