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
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
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
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
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
The function of the relay is to control the relay coil with a switch, then the working contact of the relay is closed or disconnected, one end of the contact is connected with the current of the main line, and the other end is connected with the electric appliance to be controlled to realize a smal... read more
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
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
1. Electromagnetic relay: An electrical relay that works by the suction force generated between the electromagnet core and the armature in the input circuit.2. Solid state relay: A type of relay in which the electronic component performs its function without mechanical moving parts, and the input a... read more
