Relay - SHORI
Industrial relays, signal relays, automotive relays, mains relays
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 significant advantages. They are inexpensive in relation to the latter and can be easily integrated into existing concepts. Furthermore, they allow galvanic isolation within circuits without much effort.
Our partner SHORI offers relay variants for the following application areas:
- Automotive relays
- Mains relays
(e.g. for consumer electronics) - Industrial relays
- Switch cabinet relays
- Signal relays
Contactors are in principle also a relay variant, but designed for high voltages and power. Contactors are currently not yet included in our product range.

Selection criterion "contact type"
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 not switched or is open in the idle state. The normally open contacts only close when a current flows in the control circuit.
Normally Closed (NC):
The NC contact is not connected or is closed in the idlestate. The normally closed contacts only open when a current flows in the control circuit.
Changeover (CO):
A relay with changeover contacts can do both. There are normally open (NO) contacts and normally closed (NC) contacts. When a current flows in the control circuit, the respective normally open contact changes from closed to open or from open to closed.
Technical developments in the relay market
In recent years, there have been a number of innovations in the industrial control, automotive and signal relay markets that have improved the performance and functionality of relays.
- Smaller relays with limited space available
- Relays with high quality materials and manufacturing technologies designed for high loads
- Relays with low current consumption
- Special relays designed for use in harsh environments, offering higher reliability with lower risk of failure.
- Relays with higher signal transmission rates
- Relays with integrated functions such as overload and short-circuit protection
