Help me press a button and keep it held


#1

arm needed or solenoid to move forward three cm and keep a button pressed down until
our command tells it to release


#2

The typical control method is to control whatever it is that the button activates.

If the button is mechanical, then the command signal drives a pneumatic or electric actuator or even a mechanical solenoid which in turn drives linkage to accomplish the same task as the button movement.

If the button is electrical, then the command signal drives the coil of a relay. The relay’s contacts take the place of the switch in the circuit.

If you really need a mechanical solenoid, you can Google vendors for solenoids, which are typically available from electronic component distributors.
