A switch assembly is disclosed which can serve as a custom night light and a light switch assembly with a battery back-up system that automatically unlocks in the event of a power failure. The switch assembly can be removed from an electrical box for mobile emergency use as a flashlight. The assembly can also have a mini-membrane switch, which when actuated, can emit or transmit a RF/Microwave signal to outside emergency response personal, providing location information to the response personal. The personal locator system can use battery back-up power to communicate with established emergency response frequencies.
