Feature(may vary by option.)
●Tpye A: The coil resistance is 110 ohms, and the voltage can be 5V-12V. The filter can be switched at the moment of power-on, and the current state will be maintained after power-off. You only need to change the positive and negative poles of the power supply to turn it on or off.
●Tpye B: use voltage 3-5V
●Tpye C: is driven by a miniature DC motor, the forward and reverse motor can open or close the shutter
●Tpye D: The shutter is opened by a rotating electromagnet. The rotor inside is a powerful magnet. There are 2 sets of coils on the stator. The effect is the same. The following is the test result of my own, for reference only. The resistance of the A coil is 120 ohms. It is better to use 3V-5V when it is energized. The shutter opens when it is energized, and closes when it is disconnected. The operating current is 25mA-40mA.

The shutter opens when it is energized, and closes when it is disconnected. The operating current is 25mA-40mA. The resistance of the B coil is 500 ohms. It is better to use 5V-12V when it is energized. The shutter opens when it is energized, and closes when it is turned off. The working current is 10-24mA.
