Motor starters and contactors are motor-starting devices.

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

DC motors are most commonly used in variable speed and torque applications.

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.

Snap action switches are mechanical switches that produce a very rapid transfer of contacts from one position to another.

Ground fault relays protect electrical equipment from ground faults.

AC motors include single, multiphase, universal, induction, synchronous, and gear motors.
