Claim 15:
16. A bi-stable solenoid comprising:
a housing;
a wire coil including a first coil bay and a second coil bay arranged within the housing;
a permanent magnet arranged between the first coil bay and the second coil bay;
an armature slidably arranged within the housing and moveable between a first armature position and a second armature position;
a pin at least partially extending out of the housing and moveable relative to the armature, the pin being moveable between an extended position and a retracted position; and
a spring biased between the armature and the pin,
wherein, when the armature is moved from the first armature position to the second armature position, the spring applies a force onto the pin, thereby biasing the pin toward the extended position, and when the armature is moved from the first armature position to the second armature position and the pin encounters an obstruction, the spring continues to bias the pin toward the extended position until the obstruction is removed and the pin is allowed move to the extended position.
