摘要： The present disclosure relates to a method for resetting life diagnosis alarm of a contact of a contactor, including the following steps:
Step A: detecting a reset signal by a microcontrol unit;
Step B: when the microcontrol unit has detected the reset signal, checking the state of the diagnosis alarm through the microcontrol unit;
and when the diagnosis alarm is in an active state, the microcontrol unit:
Step C: controlling the indicator to give a first indication signal for confirming a reset operation of the diagnosis alarm;
Step D: resetting life diagnosis data;
Step E: controlling the opening and closing of the contact of the contactor through an actuator.-

摘要： Embodiments of the present disclosure provide a control method and a control device for an electric switch, and an electric switch. The control method includes: obtaining a voltage signal representing a control voltage, the control voltage input to the electric switch and applied to an electromagnetic assembly of the electric switch via a regulation device of the electric switch; determining, based on the voltage signal obtained, a target control parameter for the electromagnetic assembly, the target control parameter comprising at least one of a target voltage and a target current; and generating, based on the target control parameter determined, a control signal for the regulation device, to cause the electromagnetic assembly to drive a movable contact of the electric switch to contact a static contact of the electric switch. The solution of the present disclosure can effectively reduce wear of contact points of contacts, to thus prolong the service life of the electric switch.
