1.A contacts
A contact is a contact in which the two contact terminals are separated (OFF) when the switch is not operated, and closed (ON) when the switch is operated. If you want to start the load by operating the switch, you can use the A contact. The circuit is a circuit that uses a contact, and the light does not turn on when the switch is not operated (pressed), but the light lights up after the switch is operated
2.B contacts
The contact specifications of the B contact are reversed from the A contact. In other words, the two contact terminals are closed (ON) when the switch is not operated, and separated (OFF) when the switch is operated. In the circuit, the light turns off when the switch is operated (pressed) and on when it is not operated. When you want to stop the load operation by operating the switch, you can use the B contact.
3.C contacts
The C contact is formed by combining the A contact and the B contact into a single switch. The terminals of the c contact are common terminal (COM: common), normally closed terminal (NC: normally closed), and normally open terminal (NO: normally open). When the switch is not operated (pressed), the common terminal and the normally closed terminal are in contact, and when the switch is operated (pressed), the common terminal and the normally open terminal are in contact. The C-contact is used when switching between two circuits by switching operation. to the root of the relay. For the welding of non-sealed relays, it is necessary to prevent solder from flowing into the relay, which directly affects the contact reliability of the relay.

Omron relays – the role of intermediate relays
1. Replace small contactors
The contacts of the intermediate relay have a certain load capacity, and when the load capacity is relatively small, it can be used to replace the use of small contactors, such as electric roller shutters and the control of some small household appliances. Such an advantage is that it can not only serve the purpose of control, but ...
