Abstract
404,058. Retractive switches. HARDYPICK, Ltd., Heeley, Sheffield, and HURD, F. W., 70, Cunningham Park, Harrow, Middlesex. July 30, 1932, No. 21554. [Class 38 (v).] A plug member 19 carrying contacts 16, when inserted in a housing 4 containing contacts 13 associated with a spindle 5, acts upon a spring 10 on the spindle so as to move the latter into a position in which the circuit is not completed. The spindle 5 is then moved axially by a trigger 7 to close the circuit. In the form shown the movement of the spindle is communicated by a spring 9 to a plate 12 carrying the contacts 13 which are thereby advanced to engage the contacts 16. If a remote control switch is employed, the spindle is further advanced after engagement of the contacts to complete a pilot circuit for operating the remote switch through a contact 20 and the spindle itself. In a modification the contacts 13, 16 meet when the plug member 19 is inserted, only the spindle being moved by the trigger to close the pilot circuit. The housing is mounted tangentially on a motor casing 2 of the portable drilling machine described in Specification 403,996, [Group XXII].
