Abstract
939,601. Two-part couplings combined with switches. BASSANI S.p.A. May 13, 1960 [May 16, 1959], No. 16977/60. Class 38 (1). [Also in Group XXXVII] The interlocking cover 2 of a switch and fuse unit is extended to protect a combined socket for a plug connector 24. The cover 2 carries stirrups 7 which are engaged by catches 5 when the lever 3 is moved to the " ON " position, thereby locking the cover and preventing access to fuses 1. When the lever 3 is moved to " OFF " the cover 2 may be raised and spring plates 6 prevent movement of catches 5 (and thus lever 3) to the " ON " position. Spring- loaded clip contacts (Fig. 3, not shown) are arranged to be engaged by pins 11 passing through openings 10<SP>1</SP> when plug 24 is inserted in recess 14. When it is shut down the cover 2 encloses the plug 24, and a tongue 20 on a spring- loaded catch plate 17 engages a slot 16 in an earthed post 15 which passes through a hole 28 in plug 24. Thus the plug 24 cannot be disengaged (or inserted) unless the switch lever 3 is "OFF" and a hand grip 19 is pressed to release the tongue 20, allowing cover 2 to be lifted.
