Abstract
An actuator, which find exemplary use in connection with a safety system which aims to stop powering of a boat by an engine or sail if a person falls overboard. The actuator stores energy in a main spring which is manually created by pushing linearly on an actuator rod which extends from the actuator housing. The main spring is captured between two concentric sleeves one of which sleeves is fixed to the housing. A low power coil is energizes a magnetic shuttle to cause linear motion of a shuttle against urging of small spring contained within the bore of the shuttle. Movement of the shuttle enables radial motion of balls from a position where the sleeves are locked together to one which enables one sleeve to move under force of the main spring, and thereby move the push/pull rod and act on an object to which the actuator is connected.
