Intrigued - how come so little?


The solenoid doesn't hold the door open directly - it just holds a
latch inside the closer which stops the closer operating.

The solenoids which attach to the wall and are no part of the door
closer mechanism probably use more.


This is a solenoid on a wall, separate to the closer.
