Non-Latching and Latching
An electromechanical Relay (Non Latching) is an electrical switching device. Its function corresponds to a mechanical switch, which is electrically actuated.
The main advantages are the electrical isolation of the driving system and the load side, the insulation resistance of the open contacts, as well as the low resistance of the closed contacts.
Functions:
