| Embodiments of the present invention provide a power supply module and a soft start method. The power supply module includes an input detection circuit configured to output a first notification signal to a trigger drive circuit when it is determined that the power supply module receives a power supply signal; the trigger drive circuit configured to, upon receipt of the first notification signal sent from the input detection circuit, wait for a predetermined duration without sending a drive signal to a current limiting circuit, and to send the driver signal to the current limiting circuit when the predetermined duration elapses; and the current limiting circuit configured to limit a current on a Direct Current (DC) bus of the power supply module when the drive signal is not received by the current limiting circuit, and not to limit the current on the DC bus upon receipt of the drive signal. | ||||||

| An electromagnetic relay according to the present invention is applicable, for example, to a flasher relay to be mounted in automobiles, autobicycles or the like. When a driver of the automobile turns on the switch for the winker, the winker lamp is turned on and off and at the same time, a sound is generated to inform the driver of the fact that the winker lamp is being operated. | ||||||

| A vibrating reed selector is disclosed in which a unitary motorcontact unit is encapsulated in a protective housing. The motorcontact unit contains a contact assembly, a motor assembly and an end magnet all of which are joined in a rigid structure. The contact assembly includes a ceramic circuit board rigidly attached to the end magnet at one end, two vibrating tines which carry two moving contacts and two contact brackets which carry two fixed contacts. The motor assembly includes a coil wound bobbin and a core which extends through the bobbin and which is rigidly attached to the end magnet at one end and the circuit board at the other.
