Abstract

150,646. Smith, A. C. March 26, 1920. Switches; actuating.- A switch in which the contact-member in its movement always remains parallel to the fixed contacts has a contactcarrying plate 6 with insulated contacts 14 which are interconnected by fuses, formed with lateral extensions 7 at each side which constitute the parallel-moving links of parallelogram linkages 11, 4, 7, 8 of which the member 11 is fixed, the link 4 being pivoted about the rotary operating-spindle 2 of the switch. The switch is operated by rotating the spindle 2, which carries a driving-member 12 in the form of a plate having a cut-away portion which engages a rod 3 joining the similar links 4 on each side of the contact-carrying member. Quick action may be provided and the cut-away portion of the driving-pla,te enlarged so as to give a lost-motion drive for the quick action. Additional fixed contacts may be arranged so that the switch may function as a change-over switch.
