AI Technical Summary
Existing power distribution systems for electromagnets in pushbuttons fail to ensure independent operation, efficient current conversion, and fault current elimination, leading to unnecessary power consumption and lamp activation issues.
A power source is split to supply four pushbuttons with equal outgoing current, converted by step-down modules to different amperages and voltages, ensuring independent electromagnet operation, zero current during keying, and fault current elimination.
Enables independent electromagnet operation, reduces power consumption, and prevents unintended lamp activation by managing specific currents and fault currents effectively.
Abstract
Description
[0001] A power source is split five times to supply four pushbuttons, each equipped with an electromagnet, from which current of the same magnitude and voltage is drawn (hereinafter referred to as outgoing current), which is subsequently converted by different step-down modules into currents with different amperages and voltages at the same power output. as well as for supplying individual electromagnets in a switched state, hereinafter referred to as magnet supply current.
[0002] In the keyed state, the magnets should function independently of the keying for outgoing current to the step-down modules.
[0003] If a button is pressed before the built-in electromagnet is supplied with magnetic supply current, a zero current should be generated due to the higher power consumption, as is known as a consequence of connecting devices while a computer system is operating. before the power is switched back on.
[0004] The electromagnets in the unactivated pushbuttons should, during the zero current phase, be moved by springs into a non-conductive, neutral position or remain in that position and not conduct any outgoing current when the current is switched on again.
[0005] An electromagnet in a momentary switch should exert magnetic force after the current is switched back on and remain in a current-conducting position even after the switch is released.
[0006] After passing through the step-down modules, the outgoing current, in conjunction with the cables of the other non-current-supplying pushbuttons and step-down modules, should have a conductor connection through four circuit boards.
[0007] The circuit boards should be designed such that they require different specific currents for their function. The specific current for each function should be equal to the different specific output currents of the pushbuttons.
[0008] If a circuit board is supplied with a specific current for its function, it should make a connected lamp light up; if a circuit board is not supplied with a specific current for its function, it should not make a connected lamp light up.
[0009] Potential fault currents on the circuit boards not supplied with power should be eliminated.
