05704-A-0131 继电器的接线法分为两种：一种是单触点继电器接线法，另一种是双触点继电器接线法。

05704-A-0131 单触点继电器只有一个静触点和用导线与用电设备组装的动触点，一根导线是电源的中线，另一根导线是控制线路。当开关闭合时，动触点与静触点闭合，电流从电源中线流入继电器，经过动触点和静触点，从负载回到电源负极，构成一个回路。

05704-A-0131 双触点继电器具有一个静触点和两个动触点，一个动触点与静触点断开，另一个动触点与静触点闭合。它有两根导线，一根是电源的中线，另一根是控制线路。当开关闭合时，一组触点断开，另一组触点闭合。

双触点继电器是一种电子元器件，是一种在电路中作为开关电器使用的组件。通常用于控制电动机、灯光设备等大功率电器的开关控制。其功能是通过控制电磁线圈，产生磁场使机械触点发生吸合或断开动作，从而控制电路中的大功率电器完成开关控制。

05704-A-0131 双触点继电器在电路中起到信号放大、切换和保护的功能。与普通的单触点继电器相比，双触点继电器具有更加稳定和可靠的电路控制能力。

继电器与接触器的区别：

定义不同：继电器是自动电器，主要用于距离接通和分断容量控制电路，在电力驱动中供控制、信号转换用；接触器分交流器和直流器，常用于电力、配电与用电场合，可到控制负载的电器。

作用不同：继电器作用是信号检测、传递、转换等，通断的电路电流相对来说较小，主要用在控制电路里和弱信号；接触器用来接通或断开的，容量大的接触器带有灭弧罩，不会超过5A，而小型继电器的触头大概只需1A或2A。

触头开闭不同：接触器主要用来接通或断开功率比较大的负载，常常用于主电路中，可带有连锁接点表明主触头的开闭情况；继电器常用于电气控制电路中，用来扩展微型或小型继电器的触点容量，作驱动较大的负载。

The wiring method of 05704-A-0131 relay is divided into two kinds: one is the single-contact relay wiring method, and the other is the double-contact relay wiring method.

05704-A-0131 Single contact relay has only one static contact and a moving contact assembled with a wire and electrical equipment, one wire is the middle line of the power supply, the other wire is the control line. When the switch is closed, the moving contact and the static contact are closed, and the current flows into the relay from the middle line of the power supply, passes through the moving contact and the static contact, and returns from the load to the negative terminal of the power supply to form a loop.

05704-A-0131 Double contact relay has one static contact and two moving contacts, one moving contact is disconnected from the static contact, and the other moving contact is closed from the static contact. It has two wires, one is the Central Line of the power supply, and the other is the control line. When the switch is closed, one set of contacts is opened and the other set of contacts is closed.

A double contact relay is an electronic component that is used as a switching device in a circuit. It is usually used to control the switch control of high-power electrical appliances such as motors and lighting equipment. Its function is to control the electromagnetic coil, generate a magnetic field to make the mechanical contact suction or disconnect action, so as to control the high-power electrical equipment in the circuit to complete the switch control.

05704-A-0131 Double contact relay plays the function of signal amplification, switching and protection in the circuit. Compared with ordinary single contact relay, double contact relay has more stable and reliable circuit control ability.

The difference between relays and contactors:

Different definitions: Relays are automatic appliances, mainly used for distance connecting and breaking capacity control circuit, for control and signal conversion in electric drive; Contactor is divided into AC and DC, often used in power, distribution and electricity applications, can control the load of electrical appliances.

Different functions: the relay function is signal detection, transmission, conversion, etc., the circuit current on and off is relatively small, mainly used in the control circuit and weak signals; Contactors are used to make or break, high-capacity contactors with arc extinguishers do not exceed 5A, and small relay contacts only need about 1A or 2A.

Contact opening and closing different: the contactor is mainly used to connect or disconnect the relatively large power load, often used in the main circuit, can be with a chain contact to indicate the opening and closing of the main contact; Relays are often used in electrical control circuits to expand the contact capacity of micro or small relays to drive larger loads.
