Abstract
A battery-sparing retail/home circuit for a sensor includes first and second switch systems in parallel. The first switch system includes a first user-operable switch for energizing a first circuit. The first user-operable switch is biased to an open orientation for opening the first circuit and movable to a closed orientation for closing the first circuit. The first user-operable switch is always operable to close the first circuit. The second switch system includes a second user-operable switch in a series circuit with a sensor-operated switch. The second user-operable switch is accessible by a user only after purchase of the retail/home circuit and is movable between an off orientation opening the series circuit and an on orientation rendering the series circuit dependent on the sensor-operated switch only.
