Abstract
An electrically or manually actuated locking device comprising a magnetic reed switch as a sensor to monitor whether or not the device is locked. The reed switch is mounted on a circuit board to make a sub-assembly and the sub-assembly is coated with a plastic or other synthetic material which is impermeable to water and/or oil and which provides a degree of mechanical protection from breakage. The coated sub-assembly is then mounted within a housing incorporating the locking device. A pivotable magnet carrier which pivots when the bolt of the locking device is engaged causes the reed switch to be actuated.
