Abstract
A half-automatic switch is operated in concert with a movement detecting sensor, and is also manually driven to supply power to an electric apparatus. The driving of the half-automatic switch is stopped when it is manually turned off or a signal from the movement detecting sensor is not provided. When the driving of the half-automatic switch is stopped, it is again manually driven irrespective of whether the signal from the movement detecting sensor is provided.
Claims20
A half-automatic switch that is connected to a movement detecting sensor and supplies power to a load unit using electrical energy, the switch comprising:
- an input switch;
- a switch unit for supplying power to the load unit;
- and
- a controller that drives the switch unit to supply the power to the load unit when the input switch is operated and stops the driving of the switch unit to cut the power supplied to the load unit when a signal from the movement detecting sensor is not provided in a state in which the switch unit is driven,
- wherein the controller drives the switch unit according to whether the input switch is operated, irrespective of whether the signal from the movement detecting sensor is provided, when the switch unit is not driven.
A half-automatic switch that is connected to a movement detecting sensor and supplies power to a load unit using electrical energy, the switch comprising:
- a switch unit for supplying power the load unit when being driven;
- and
- a controller that stops the driving of the switch unit to cut the power supplied to the load unit when a detection signal from the movement detecting sensor is provided in a state in which the switch unit is driven,
- wherein the controller maintains stopping the driving of the switch unit, irrespective of the detection signal from the movement detecting sensor, when the switch unit is not driven.
