Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply.

Motor starters and contactors are motor-starting devices.

AC motor starters are used to turn-on and turn-off electric motors and motor-controlled equipment.

Electrical contact and electrode materials are soft, high conductivity, oxidation resistant materials used in circuit breakers, relays, and for EDM applications

DC motor starters combine a controller (most often a contactor) with overload protection, allowing a motor or motor-controlled equipment to be turned on and off

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other

Aerospace contactors are high-performance, high-capacity circuit controls designed for aerospace applications
