发明名称 Sewing machine
摘要 A sewing machine has a base plinth with an overhead portal that pivots against the base for maintenance access. The sewing machine electric motor is linked to the power supply via a gravity-operated switch (12) in the portal housing. When the portal moves from the operating position (A) to the maintenance position (B) the switch automatically interrupts the electricity supply. The switch is a gravity-operated magnetically induced reed switch located in the portal housing at the same height as the drive shaft and locate on a printed circuit board. The portal housing consists of two shelf halved bonded together.
