Abstract: A hinge switch (20) has a unitary plastic body (21) that can be formed by injection molding or extrusion. The body (21) has a base (22) that holds a magnetic field sensor (48). The base (22) is fastened to a support structure by a plurality of fasteners. The base (22) is connected to an arm by an elastic U-shaped portion (24) of the plastic body that acts as both a hinge and a biasing member. The arm positions an activation magnet (58) over the base (22) and the sensor. The arm does not block access to fasteners that mount the switch to the support structure.
