Relays and Contactors

Aircraft relays, contactors and related electrical switches are arranged by complete designation and recorded switching role. This catalogue group includes electromagnetic relays, thermal relays, higher-current contactors and manually operated switching devices. Similar contact layouts or rated voltage do not make different executions interchangeable.

Electromagnetic, thermal and manual switching devices

The range contains 8E-series electromagnetic relays, 4463AT-48 thermal relay, TKS contactor positions and switches from the VG and PPG families. A designation may encode contact arrangement, load class, coil data or series. Preserve every character and value rather than reducing the search to a generic relay type.

Coil, contacts and circuit duty must agree

Correct identification may require coil voltage, contact current, pole and throw arrangement, operating mode, mounting and connector details. The circuit function and technical documentation should support the choice. Never infer an alternative solely because the device fits mechanically or carries a nearby family number.

• copy the complete relay or contactor marking;
• state coil voltage and contact rating;
• identify the controlled circuit when known;
• provide terminal and label photographs;
• specify quantity and document requirements.

Request the correct switching component

Use the precise product card to ask for confirmation of identity, condition, documentation, price and lead time. Circuit-protection devices are listed under Aircraft Circuit Breakers. Operator interfaces and switching assemblies are available in Aircraft Control Panels.
