ABSTRACT:
Apparatus for rapidly changing the state of a device from an active state to an inactive state. The apparatus includes an inner member slidably contained in an outer member. The member is connected to an actuator and the other to a control for changing the state of a device. A latch mechanism normally holds the two members locked together so that the control means responds to the actuator. When a potentially dangerous situation is sensed, the latch mechanism is opened and the two members are rapidly forced apart by a heavy release spring thus rapidly changing the state of the device from an active state to an inactive state.
