PURPOSE: An electronic actuator and an exposing condition switching device are provided to overcome the restriction of an exposing condition switching member or a dummy filter by creating huge driving power through the electronic actuator of oscillating type. CONSTITUTION: An electronic actuator of oscillating type comprises a housing(10), an upper cover(20), a moving stator(100), a coil(210), and a yoke(220). The moving stator is shaken by providing electrical power to the coil for excitation. The moving stator comprises a first light exposing part and a second light exposing part. The moving stator is shaken based on an oscillating support axis(13) and an oscillating bearing hole(22). The oscillating support axis is installed in the housing and the upper cover which are located in the outer side of the domain surrounded by the coil for excitation. The coil surrounds a permanent magnet(114) of the moving stator and is intercrossed on the oscillating plane of the permanent magnet. |
