Title: Improvements in auxiliary switches such as inching switches for electric motor starters
IPC: H01H50/54
Filed: 1955-12-14
Abstract: 798,999. Electrically-tripped switches; pressbutton retractive switches; controllers. CRABTREE & CO., Ltd., J. A., and WINTLE, T. D. G. Oct. 29, 1956 [Dec. 14, 1955], No. 35856/55. Classes 38 (3) and 38 (5). An auxiliary switch constructed similarly to that described in Specification 633,395 and associated with the contactor disclosed in Specification 633,393, comprises a press-button 1 returned by a spring 6 and slidably carrying a pair of bridging contacts 2, 3 urged apart by a spring 4. Normally, the contact 3 bridges fixed contacts 5 in the circuit of the start button switch (not shown) so that when the latter is operated the contactor coil is energized to attract armature 14 to the magnet 14a, the armature then mechanically maintaining the contacts of the start-button switch closed. The button 1 serves as an inching button for motor control and has pivoted thereto at 8 a catch lever 9 biased by a spring 15 so that it normally abuts the top of a projection 10 on the switch casing. On depression of the button 1 the contact 3 opens and contact 2 bridges fixed contacts 7 to energize the coil, the down-turned end 9a of the lever 9 moving over the projection 10 and beyond it to the left so that the spring 15 pivots the lever 9 counter-clockwise. On release of the button 1 the contact 2 opens but contact 3 cannot immediately close since the projection 10 arrests the lever end 9a; however, as the armature 14 approaches its " off " position an ear 12 thereon engages the lever arm 9b whereby the lever is tilted to disengage the projection 10 and the parts are restored to the normal position shown. The arrangement ensures that the contact 3 cannot close before the armature has permitted the contacts of the startbutton switch to open and thus prevents undesirable energization of the coil when " inching."
