WebRelay Symbols and Electromagnets. The relay are switching electrical devices activated by signals. Most of the time, a small voltage or current is used to switch other voltages or higher currents that may be electromechanical or fully electronic type. The electromagnetic controls are activated thanks to electromagnetic fields generated by ... WebForm A contacts ("make contacts") are normally open contacts. The contacts are open when the energizing force (magnet or relay solenoid) is not present. When the energizing force is present, the contact will close. An alternate notation for Form A is SPST-NO.
