Abstract

1505870 Electromagnetic contactors; vacuum switches WESTINGHOUSE ELECTRIC CORP 9 June 1975 [20 June 1974] 24607/75 Heading H1N The movable contact stem 150 of a contact set of a multipole vacuum or air break switch is pivotally connected at 132 to a lever 105 having a fixed pivot 107 and its other end 130 engaged by one end of a compression spring on an actuator 120 coupled by link 114 and common shaft 69 to an operating electromagnet (Figs. 3 and 5, not shown). Current from the contact stem 150 passes through a part flexible double loop 221, 195, 222 to a terminal 45 and acts on a movable arm 136 which is also pivoted to the stem 150 of 132 and in the actuated switch position (Fig. 6) engages an abutment 122 of the actuator 120 so that whilst the operating coil is energized any heavy currents in the double loop 221, 195, 222 cause the arm 136 to act on the stem 150 in a contact closing direction but when the operating coil is de-energized whilst heavy currents are being carried, the arm 136 is moved to act on the pivot 132 as well as abutment 122 and assist in contact opening to break any weld between the contacts of a vacuum switch 103.
