Document Type and Number:
WIPO Patent Application WO/2009/149655
Kind Code:
A1
Abstract:
There is a power switch device realizing zero power consumption during standby condition, it includes manual acting switch device (1), power input (7), magnetic latching relay (3), coil drive circuit and power output (8); the both ends of the coil of the magnetic latching relay (3) are connected to the coil drive circuit; the manual acting switch device (1) is used for switching the contact switch (32) off or closed so that the power input (7) and the power output (8) are disconnected or power connected; the coil driver circuit is used for generating the first pulse and driving the coil of the magnetic latching relay (3) to make the contact switch (32) off or closed when receiving the control signal so that the power input (7) and the power output (8) are disconnected or power connected.
