The FEMS usually includes the electromagnetic mechanism (EMM)--the main contact module and the actuator, which provides the execution of switching operations by contacts (in contactors, the actuator's role is most often performed by a forced unpolarized electromagnet with a rotating spring) and a control device (CD) that performs changes in the windings' control circuit to provide the required values of currents both during operation and in the final state.

An existing traditional electromagnetic switch that takes the role to interrupt electricity through the mechanical switching when it conducts an overcurrent is composed of both an electromagnet called the magnetic contactor, which connects or disconnects signals of main power, and the thermal overload relay with an on-off switching function controlled by temperature.
Because it's a device that measures the electromagnet wave's angle of arrival in free space, signal amplitude reaching a receiving antenna can be changed by various factors, and it results DF accuracy errors.
