Abstract:
A sensor for detecting movement, comprising:a first conductive member connectable to a first electrical contact;a second conductive member spaced away from said first conductive member and being connectable to a second electrical contact;a third conductive member that is in constant electrical communication with said first conductive member, and is movable from a switch-off position in which said third conductive member is spaced away from said second conductive member, to a switch-on position in which said third conductive member electrically communicates said first conductive member with said second conductive member; andan insulating member attached to said third conductive member, and being contactable with a surface of a support member, said insulating member causing said third conductive member to move from the switch-off position to the switch-on position if an attempt is made to slide the sensor along the surface of the support member.
