Questions & Answers about Accionamos el pulsador.
Accionamos is the 1st person plural form of accionar.
It can be:
- present indicative: we activate / we operate / we press
- preterite: we activated / we operated / we pressed
So on its own, accionamos is grammatically ambiguous between present and past. The context normally tells you which one is meant.
In technical writing, the present reading is often very natural.
Spanish usually drops subject pronouns when the verb ending already makes the subject clear.
- accionamos already tells you the subject is we
- so nosotros accionamos el pulsador is possible, but usually unnecessary
You would add nosotros only for emphasis, contrast, or clarity:
- Nosotros accionamos el pulsador, no ellos.
