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.
Claims7
A battery-sparing retail/home circuit for a sensor comprising:
- (A) first switch means including a first user-operable switch for energizing a first circuit, said first user-operable switch being biased to an open orientation for opening the first circuit and movable to a closed orientation for closing the first circuit, said first user-operable switch always being operable to close the first circuit;
- and
- (B) second switch means including a second user-operable switch in a series circuit with a sensor-operated switch, said second user-operable switch being accessible by a user only after purchase of said retail/home circuit and movable between an off orientation opening the series circuit and an on orientation rendering the series circuit dependent on said sensor-operated switch only;
- said first and second switch means being in parallel.
A battery-sparing retail/home circuit for a sensor comprising:
- (A) a normally open user-operable pressure-sensitive biased switch for closing a first circuit;
- (B) a normally open sensor-operated switch for closing a second circuit parallel to said first circuit;
- and
- (C) a three-way switch accessible by a user only after purchase of said retail/home circuit and movable among a first orientation energizing said first circuit, a second orientation energizing said second circuit, and a third orientation simultaneously energizing both circuits, said three-way switch initially being in said first orientation.
