DRUCKKNOPFBETAETIGTER UEBERSTROMSCHUTZSCHALTER.

摘要

The switch has a bimetal contact arm (4) and a fixed contact arm (5) both embedded at their middles (8) in a shape-retaining cast plastics insulator acting as a base (3). The bimetal arm has a weakened point (18) for adjustment at the place where it leaves the base. The contact and fixed arm are held in the base over a distance at least one third of their total length. The fixed contact arm has a bend embedded in the base. The bimetal contact arm has a waisted zone embedded in the base. The weakened point is a punched hole at right angles to the main plane of the arm.
