ABSTRACT:
The invention is a timer assembly (10, 100) to be interposed between a battery (12) and an electrical load (14) having a device switch (16). A timing cycle is initiated upon detection of closure of the device switch (16). The timer (10, 100) will terminate the current flow after the timing cycle. The timer assembly (10, 100) includes a first embodiment (10) to be connected in parallel with the battery (12) and electrical device (14), and a second embodiment (10, 100) connected in series with the battery (12) and the electrical load. Upon closure of the device switch (16), a detector (42, 44, 46) produces a pulse initiating the timing cycle. The timing cycle may be realized by discharging a storage capacitor (38, 40) or by a timer chip (36) controlling an electronic switch (26, 28, 30, 32) within the timer assembly (10, 100) to connect and disconnect the battery (12) to the load (14).
