摘要:
An emergency lighting device includes an internal battery, a switching mechanism, and one or more light sources. The light sources are electrically coupled to the internal battery through the switching mechanism. The switching mechanism includes a first contact and a second contact. Additionally, the switching mechanism is configured to receive an external mechanical disconnect male jack to electrically disconnect the light sources from the internal battery. In certain embodiments, the emergency lighting device is also electrically coupled to an external power source and includes a circuit breaker for providing power to the light sources from the external power supply during normal operation and for automatically providing power to the light sources from the internal battery in the event that power from the external power source fails.
