Latching Relays

Latching Relays for Automation and Energy-Efficient Switching

Latching relays are key components in modern electrical control systems where low energy consumption and memory switching are required. At Bank of Lamps, we stock mechanical and magnetic latching relays from certified European brands — ready for wholesale distribution across Germany, France, the Netherlands, the UK, Spain, Baltics, and Belgium.

From micro latching relay units for compact applications to 12V and 24V latching relay models for automation and smart building setups — we deliver directly from EU warehouse stock.

What Is a Latching Relay?

Unlike standard relays, a latching relay circuit retains its last state after the control signal is removed. It doesn't require continuous power to remain on or off — ideal for energy-saving and memory-based applications.

There are two main types:

• Magnetic latching relay – uses a permanent magnet to hold the position
• Mechanical latching relay – relies on a bistable mechanical system

These relays are widely used in building automation, smart lighting, industrial machines, and control panels.

Available Models – 12V, 24V, Solid State and Compact Relays

Our assortment includes:

• 12V latching relay (coil-based, bistable, plug-in types)
• 24V latching relay for industrial automation and logic circuits
   
• Solid state latching relay with no moving parts (low maintenance)
   
• Micro latching relay for space-constrained boards
   
• 12 volt latching relay and DIN rail types for smart homes and lighting controls
   

Voltage ranges: 5V / 12V / 24V / 230V AC/DC
Contact ratings: 8A, 16A, 32A
Pole types: SPST, SPDT, DPDT
Mounting: DIN rail, PCB, plug-in socket, screw mount

Relay Brands in Stock

We stock latching relays from verified EU manufacturers with proven industrial quality:

• Finder – 26 & 27 series (bistable relays with coil memory)
   
• ABB – ESB/CR-M series with optional mechanical latching
   
• Siemens – Sirius 3RH series for control circuits
   
• Schneider Electric – Zelio and TeSys ranges
   
• Theben – modular DIN relays for building automation

All products conform to EN 61810 standards, CE-certified, and designed for EU grid requirements.

Application Areas for Latching Power Relay Systems

Latching relays are common in:

• Lighting control systems (corridor switching, staircases, hallways)
   
• Smart home modules (Z-Wave / KNX control with bistable states)
   
• Motor control (energy-saving switching for pumps and valves)
   
• Alarm and security panels (low power contact retention)
   
• Industrial PLC setups (with state-memory in power failure scenarios)
   

They reduce power consumption in circuits where a continuous coil load is undesirable — especially in projects requiring latching power relay logic.
