Abstract
An inclination responsive switch is provided for repetitively actuating and deactuating a high-current load, such as a low-voltage lamp in an automobile. A gravity responsive device produces a low-current output signal, which has a first state when the gravity responsive device is in a first inclination position and a second state when the device is in a second inclination position. A semiconductor switching device has a low-current input terminal connected with a low-current output of the gravity responsive device. The switching device amplifies the low-current electrical signal to produce a high-current electrical signal in order to supply high current to a load connected with the high-current output terminal of the switching device to actuate the load in one inclination position and terminates the high current to deactuate the load in the other inclination position.
