Claim 0:
1. 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 within the housing;
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 slidably engaged by the armature; and
a spring biased between the armature and the pin,
wherein when the pin encounters an intermediate position between a retracted position and an extended position due to the pin engaging an obstruction, the spring is configured to maintain a biasing force on the pin until the obstruction is removed, and
wherein the pin is slidably engaged by the armature such that when the pin is prevented from displacing to the extended position by the obstruction, the armature is allowed to shift from the first armature position to the second armature position.
