Relay Type
What are different types of relay?
There are a lot of different relay types depending on the operating principle, applications and structural features. Here is a list of the different types of relays:
| Coaxial Relay Contactor Force-guided Contacts Relay Latching Relay Machine Tool Relay Mercury Relay Mercury-wetted Relay Multi-voltage Relays |
Overload Protection Relay Polarized Relay Reed Relay Safety Relays Solid-state Contactor Solid-state Relay Static Relay Time Delay Relay Vacuum Relays |
This page lists the different relay types which are described on Apogeeweb.
Relay Applications
What is the purpose of a relay?
Electrical relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. And meanwhile, they are used to control high voltage circuits with the help of low voltage signals. Similarly they are used to control high current circuits with the help of low current signals.
Here is the rule. Relay works on the principle of electromagnetic induction. When the electromagnet is applied with some current it induces a magnetic field around it. According to it, relays have different functions in different fields, let's check it at this page.
Relay Fundamentals
What does relay mean?
An electrical relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. In short, a relay allows circuits to be switched by electrical equipment. Relays commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts), but other operating principles have been invented, such as in solid-state relays which use semiconductor properties for control without relying on moving parts. When a relay contact is open, this will switch power on for a circuit when the coil is activated.
