Switch is a circuit that can open the circuit, so that the current interrupt or make it flow to other circuits of electronic components.The most common switch is to operate the mechanical and electrical equipment (such as: delay switch, touch switch, photoelectric switch, double control Switch, etc.), which has one or several electronic contacts. The 'closed' of the contact indicates that the electronic contact is conducting, allowing the current to flow; the 'open' of the switch indicates that the electronic contact is not conducting open and does not allow current to flow
Switch basic structure
The simplest switch has two metal called 'contact', the two contacts contact the current to form a loop, the two contacts do not touch the current open circuit. Selection of contact metal to consider its degree of corrosion, because most Metal oxide will form an insulating oxide, so that the contacts can not work properly. Selection of contact metal also need to consider its conductivity, hardness, mechanical strength, cost and whether the toxic and other factors
Sometimes the corrosion resistance of the metal plating on the contact. General will be plated in the contact surface of the contact to avoid the impact of its performance due to oxide. Sometimes the contact surface will use non-metallic conductive materials, such as conductive plastic
In addition to the contacts in addition to the contacts, there will be moving parts to make contact or non-conductive, the switch can be divided according to the different parts for the lever switch (Toggle switch), key switch, rocker switch (Rocker switch) , And the movable member may be other types of mechanical links
working principle
The power switch K2 is closed and the push button switch K1 is pressed. At this time, the crystal diodes V1 and V2 are turned on and the relay is engaged, and the power supply charges the capacitor C. When K1 is turned off, since C has been charged, And V1V2 discharge, so as to maintain the transistor to continue conduction, the relay is still connected after a period of discharge, C between the two poles down to a certain value, not enough to maintain the transistor to continue conduction, the relay was released from K1 off to the relay The time interval of release is called the delay time, which is determined by the size of R and C. Generally, when C is 100 microfarads, adjust the adjustable resistor R to obtain a delay time of 10 seconds to 90 seconds. Method, the delay time of up to 5 minutes or more. Relay on the diode in parallel to protect the role of the relay to prevent the release of power, due to self-induced high voltage damage crystal transistor

Welding circuit
1, the components do pre-treatment, tin
2, the welding relay. The relay will be inserted into the corresponding hole on the printed board. The five pins welded. Note that the welding time should be as short as possible, the solder joints should be round and small
3, welding R and C, adjustable resistor R welding and then inserted into the printed circuit board welding. Electrolytic capacitor C welding should pay attention to positive and negative pin position
