lülitas

Lülitas is the past tense form of the Estonian verb lülitada, meaning to switch on, turn on, or connect a device or circuit by using a switch. It functions as a verb form rather than a standalone noun, and it is used to describe a completed action in the past.

In usage, lülitas appears with a direct object that is being switched on or activated. For example, ta lülitas valguse sisse means “he turned the light on.” The verb can also describe turning something off by combining lülitada with the appropriate particle, such as välja, to form “lülitas välja” (turned off). The sense is determined by the accompanying particles and context.
