Assembly of switch actuator springs into housing - has torsion spring loaded and inserted into main body

摘要

A torsion spring is used to hold an electrical switch contact in a defined state. The spring is mechanically assembled in the housing under load. The automatic assembly machine has the spring loaded onto a spigot (2) and has the switch actuating stem (13) projecting. The spring is subjected to a predetermined torsional load that is applied by a cylinder actuator. Once the arm is in the correct position the end is inserted into a slot on the switch body. ADVANTAGE - Automatic loading of switch actuation springs.
