Abstract
An installation-activated, battery-powered hazard device with an on/off switch mechanism and separable into complementary portions. A first of the portions contains essentially all operative electrical circuitry, including sensor(s), a source of power, and a circuit break feature; while its complement provides various small structures or morphology that aid or facilitate closure of the break. Cooperative functioning of the structures is consistent with a stylized mating or unmating of the portions. Multiple versions of the unique multiuse or recyclable switching device are disclosed.
