A single triode consisting of a delay switch circuit resistor R, V, a base resistance (referring to the resistance between the emitter and the base of the transistor) and a capacitor C, etc., constitute an RC two delay circuit. When the button SB is pressed, V is turned on by the forward bias voltage, and the relay K is pulled. When you let go, the SB is automatically disconnected, but K is not released immediately, but it takes a while to release.

Water-cooled Capacitor

Water-cooled capacitor is supercapacitor is a capacitor with a capacity of thousands of farads.According to the principle of capacitor, capacitance depends on the distance between the electrode and electrode surface area, in order to get such a large capacitance, as far as possible to narrow the distance between the super capacitor electrode, electrode surface area increased, therefore, through the theory of electric double layer and porous activated carbon electrode.
