    The role of the magnetic latching relays

    1. Introduction to magnetic latching relaysThe magnetic latching relays is also a kind of relay, but it has more stable performance than other relays, and has a smaller volume and a stronger carrying capacity. The magnetic latching relays is essentially an automatic switch that can automatically tu... read more

    The role of the intermediate relay in the line

    In industrial control lines and current home appliance control lines, there are often intermediate relays. For different control lines, the role of three-phase relays is different. The functions of the intermediate relays are common in the following ways:1. Replace the small contactorThe contacts o... read more

  • Why can automotive relays control large currents with small currents?

    Why can automotive relays control large currents with small currents?

    To make it easier to understand, we divide the circuit into two parts, a low voltage (small current) circuit and a high voltage (high current) circuit. In the figure, the power supply, the switch S1, and the coil are low voltage circuit parts; the contacts, the load power supply, and the consumer a... read more

  • What is the role of the relay coil?

    What is the role of the relay coil?

    We should all know the role of the relay. As long as a certain voltage is applied across the coil, a certain current will flow in the coil, which will produce an electromagnetic effect. The armature will overcome the tension of the return spring under the action of electromagnetic attraction. To th... read more

    What are the production procedures for the light tact switch?

    The light touch switch mainly includes: stamping--injection--cleaning--assembly--forming--inspection and the like; and the membrane switch process is mainly: silk screen--die-cut--assembly--detection process.Both of them have high requirements on the production environment. Relatively speaking, the... read more

    General power relay working principle

    A power relay is a device that can be converted in one or more electrical output circuits when input (or excitation) meets certain specific conditions. It can be used in a neutral point direct grounding system as a directional component for zero sequence current protection. The action of the contac... read more

    Relay contact action principle

    The action of the contact can be divided into two parts: contact closure and contact disconnection, that is, the pull-in and release process of the relay, which are cyclically switched at a certain frequency to form a contact opening and closing phenomenon. There are many special physical and chemi... read more
