Industrial Relays, Mains Relays, Signal Relays, Automotive Relays, 

The first computers were still based on mechanical functions but also on relays like the Zuse Z3. The binary code used today (ON or OFF for the logical "1" or "0" in modern supercomputers can in principle also be represented by relays and was also used in this way.

Relays are electromagnetic or electromechanical switches. They are used to switch circuits on, off and over. The classic relay is an electromagnetic switch. 

Compared to fully electronic circuits and switching concepts, relays still have some essential advantages. They are inexpensive in proportion, easy to integrate into existing concepts and, above all, allow galvanic isolation within the circuits without much effort

SHORI offers relay variants for these fields of application:

  • Automotive relays
  • Mains relay
  • Industrial relay
  • Control relays 
  • Signal relay

In principle, contactors are also a relay variant, but are designed for high voltages and power. Contactors are currently not yet in our product range.

In addition to the electrical selection criteria such as coil voltage and current, load current and the mechanical design, the contact types are essential for the correct selection

Normally Open (NO): 

The normally open contact is unconnected or open in the normally closed state. Only when a current flows in the control circuit do the normally open contacts close. 

Normally Closed (NC): The normally open contact is not connected: 

The normally closed contact is not connected or is closed at rest. The normally closed contacts do not open until a current flows in the control circuit.

Changeover contact (Change Over, CO): 

A relay with changeover contacts can do both. There are normally open contacts which are switched as make contacts and as break contacts. When a current flows in the control circuit, the respective make contact changes from closed to open or from open to closed.
