Movement of a first output member is initiated relative to a second member on a non-explosive basis. A wire holds a pair of members in a first relationship until disintegrated by electrical current. The first members retain a second member in a first relationship until the wire is disintegrated. The second member is biased for movement to a second relationship when the wire disintegrates. A third pair of members is biased to retain a fourth member in a frictional relationship. The fourth member is coupled to the first output member to move the first output member. The third member is moved by the second member out of frictional relationship with the fourth member. The fourth member is biased to move the first output member when the fourth member is released by the third member. The wire and the first through fourth members are disposed in retention means so that the first and second means and the wire can be withdrawn from the retention means, or inserted into the retention means in their first relationships, without affecting the disposition in the retention means of the third and fourth members in the first relationships.
