Finder electrical relay 41.81.7.024.8240 3 A 1 Contact – miniature relay for switching circuits

Finder electrical relay 41.81.7.024.8240 is a compact electromechanical switching device with a single changeover contact rated for 3 A. Built for general-purpose switching in control panels, automation systems and household appliances, the miniature relay offers reliable on/off control of low-current circuits while occupying minimal space. The design conforms to the functional needs of applications that require a small 1-contact relay with predictable switching behaviour and long contact life under appropriate conditions.

Advantages

The relay combines a compact footprint with a clear electrical rating and simple mounting options, making it easy to integrate into existing panels or modules. Its single-contact configuration simplifies circuit design when only one switching channel is required. The electromechanical construction provides galvanic isolation between coil and contact, ensuring separation of control and load circuits and straightforward maintenance diagnostics.

Suitable for

• Control panels and distribution modules in residential and light industrial installations
• Automation systems requiring a compact switching element for signal or low-power loads
• Appliances and equipment where a single 3 A contact is sufficient for switching heaters, small motors or indicator circuits
• Replacement or upgrade of existing miniature relays with matching electrical characteristics

Key specifications

• Contact configuration: 1 changeover contact (single pole)
• Contact rating: 3 A for resistive loads
• Relay type: miniature electromechanical relay
• Intended use: low-current switching and signal-level control
• Mounting: panel or socket mounting compatible with miniature relay sockets
• Electrical isolation: galvanic separation between coil and contact

How to use

Install the relay into the appropriate socket or panel location, ensuring correct orientation and secure mechanical retention. Connect the coil to the specified control voltage and wire the common, normally open or normally closed contact terminals according to the circuit diagram. Verify that the circuit current does not exceed the 3 A contact rating and observe correct polarity and insulation practices where relevant. After wiring, perform a functional check by energising the coil and confirming reliable switching between contact states under the intended load.

Usage recommendations

For reliable operation, use this miniature relay within its rated current and voltage limits, avoid switching inductive loads above the specified rating without appropriate suppression, and choose compatible sockets or mounting accessories. Regularly inspect contacts and connections in demanding or vibration-prone environments; replace the relay if contact wear or inconsistent switching is observed.
