Abstract

The punch (3) of the press (1) houses a compression spring (7) in its upper end. The outer end of the spring (8) is covered by a cap (10) which can slide axially over the flange (6) screwed into the punch (3). The cap (10) carries a switch (13) forming part of the control circuit of the motor driving the press. The actuating load (F) is applied through the cap and is normally insufficient to compress the spring (7). Under abnormal loading the spring (7) is compressed and the switch (13) moves away from the arm (19) which is rigidly attached to the punch (3). The consequent removal of pressure from the press button (15) opens the switch (13) and cuts out the driving motor.
