Abstract: A blind rivet setting tool including a channel along which the broken mandrels of set rivets can be moved and a biasing element for biasing a blocking member into the channel for blocking the movement of a broken mandrel along the channel whereby a broken mandrel must urge the blocking member out of the way against the bias in order to move past the blocking member.

Abstract: An actuator for actuating a switch of a powered device having a plurality of positions in which the actuator is magnetically held in position. The actuator includes a first actuator portion including a magnet and a first magnetic element having a first plurality of limbs, whereby magnetic flux of the magnet is directed through the first plurality of limbs; and a second actuator portion including a second magnetic element having a second plurality of limbs for receiving the magnetic flux from the first plurality of limbs. The actuator has a plurality of positions in which limbs of the first plurality of limbs align with limbs of the second plurality of limbs thereby to couple the magnetic flux in a flux loop through two limbs of the first plurality of limbs of the first magnetic element and two limbs of the second plurality of limbs of the second magnetic element.

Abstract: A blind rivet setting tool including a nosepiece storage unit removably attached to a housing feature of the tool, wherein the nosepiece storage unit is configured to hold a plurality of nosepieces and defines a mandrel receiving opening which aligns with an exit opening of the tool such that the broken mandrel of a set rivet can be moved through the mandrel receiving opening in use; and method of using the nosepiece storage unit.

Abstract: A blind rivet setting tool including a clamping assembly for releasably clamping a nosepiece in place such that a blind rivet can bear against the nosepiece while the mandrel thereof is pulled; and a method of changing nosepieces using the clamping assembly.

Abstract: A jaw assembly for a rivet setting tool the jaw assembly including a plurality of jaws each jaw defining part of an interlocking mechanism and an oppositely located part of another interlocking mechanism wherein adjacent jaws interlock via engagement of the parts of the interlocking mechanisms of the respective jaws for enabling radial movement of the jaws relative to each other while restricting axial movement of the jaws relative to each other.
