In STEP7, the white lamp is turned on by pressing BS1 (switch 1) and is turned off by releasing the switch. In STEP8, create a circuit so that the lamp is not turned off even when BS1 (switch 1) is released.
Key point
In a "self-holding circuit", a coil is excited by current externally applied to the electromagnetic relay, an operating circuit is created by the contacts, and the current is kept flowing through the coil.
