I would like to control the locking of a gear, using a solenoid. My original idea was to simply activate the solenoid to pull back the lock (a tooth that sticks into the gear), but that means that I'd need to keep applying current to the solenoid as long as I want the gear unlocked.
Now, I'm thinking it would be better to have a mechanism between the solenoid and the gear, so that a pulse to the solenoid would unlock the gear, and another pulse would lock it. Kind of like the mechanism in a click type pen. What would be a good choice of mechanism to accomplish this, considering how solenoids have a very short stroke distance?
