When using Dongguan toggle switch, we should pay attention to the form of trigger. What are the specific ones? Let's give you a detailed introduction.

Dongguan toggle switch is only triggered in different forms. Simple circuit consists of a large capacitor, a large resistance and an insulated gate FET. When triggered, the capacitor is charged and the trigger cycle is completed. At this time, the gate capacitance of the insulated gate FET acts as a high voltage in the gate. The FET conducts and the gate leaks. One load after another, the load will work.
The resistance of the gate to the ground is very high, usually hundreds of megaohms, so the discharge is slow, so we need to add a discharge resistance, usually adjustable resistance, to adjust the delay time. The resistance is large, the delay is long, the resistance is small and the delay is short. When the capacitor is dead and the gate voltage is dead, the FET enters the cut-off state and the drain load stops working.
Users will choose different vibration switches to meet the sensitivity of their products because of the needs of different products. Generally speaking, only the sensitivity requirement has no directional requirement, so it is necessary to know the use of the user's product before recommending the type of spring switch for the user.
