O que há neste desenho
Entenda as decisões por trás dele.
01
Use seal-in auxiliary contacts to maintain coil state after momentary start pushbutton release
02
Add normally closed K1/K2 auxiliary contacts in series with opposite direction coils for electrical interlocking
03
Include overload relay NC contacts in both run circuits and a separate fault lamp rung for trip indication
Applicable to industrial motor control panels, conveyor reversers, hoists, and any reversing starter requiring safe directional interlocking and overload protection.
