Abstract

1,046,794. Electromagnetic relays-electrically tripped switches. A. O. SMITH CORPORATION. July 31, 1963 [April 19, 1963], No. 30444/63. Heading H2B. Plunger-operated bridging contact units having fixed contact members 59 extending from opposite ends also have terminal screws 65 which secure supply leads (not shown) and attach the contact unit to mounting blocks 37 of a relay frame 4. The frame 4 is secured to a case 2 and has pads 38 engaging projections 16 of a coil former 11 to urge it against a resilient pad (not shown) in the base of the case 2. An insulating actuator 29 is moulded to the armature 28 and slides in slots 33 in the frame 4. Two such frames 4 with eight contact units 5 can be used with the alternative actuator 36 shown. Buttons 35 project from the actuator 29 through holes 44 in a top plate 42 and can be manually operated. Fig. 11 shows a cover 6 which may replace the top plate 42 and is provided with a latch 71 which engages a projection 34 on the actuator 29 to retain it in the operated position. The latch 71 is released by a plunger 83 operable by an electromagnet or manual depression of nut 86.
