Отзыв о Замок шкафа ATOPLEE 12 В для ящиков, кладовых и шкафчиков - электронный, мощность 2 А, компактный размер (73 х 58 х 13 мм) от Edwin White

When I saw the video demonstration I thought for sure that it had to be bs but, it really does rocket the latch out of the lock. There's a very powerful spring that is compressed and held into place when the lock is engaged and released by the electro magnet when triggered with 12v. Disengaging the lock is very satisfying and it makes a cool metallic ping noise. Haven't used the extra wires yet for logic feedback as I only triggered it manually with a battery but, should be easy to implement triggering with a logic chip and a 555 timer in one shot mode hooked up to a button and a power transistor on the output pin to trigger the electromagnet with 12v. I'm definitely going to buy more, eventually. Quick delivery and I'm very happy with my order.
