AI Technical Summary
Technical Problem
The existing starter switch has an excessively long axial dimension, and the built-in reset spring makes it difficult to achieve weight reduction. The solder joints are prone to fatigue fracture, which affects reliability.
Method used
The reset spring is externally placed and integrally formed with the annular flange of the moving iron core, eliminating the need for solder joints. The switch components are fixed by riveting, and engagement springs and overtravel springs are used for limiting and buffering.
Benefits of technology
This effectively reduces the axial length of the starter switch, improves reliability and service life, reduces the risk of solder joint breakage, and ensures reliable circuit conduction.

Abstract
The utility model discloses a light-weight start-stop starter switch, which comprises a switch main body and a movable iron core assembly, the switch main body comprises a switch cover and a switch shell connected with the switch cover; the switch cover is connected with a first contact bolt and a second contact bolt, and a coil is arranged in the switch shell. The movable iron core assembly comprises an integrally-formed movable iron core, one end of the movable iron core is connected with a push rod, the other end of the movable iron core is connected with a pull rod, and the push rod is connected with a contact copper plate. The movable iron core is movably arranged on the switch shell, and one end of the movable iron core extends out of the outer side of the switch shell; an annular flange is arranged on the outer side of the movable iron core, the reset spring is connected to the movable iron core in a sleeving mode and located on the outer side of the switch shell, one end of the reset spring abuts against the outer wall of the switch shell, and the other end of the reset spring abuts against the annular flange. According to the utility model, the axial length of the switch main body is reduced, the light weight requirement of the starter switch is met, and the reliability and the service life of the starter switch are improved.
