Abstract

977,527. Switches, partly electromagnetic. TRIAX CO. Feb. 16, 1962 [Feb. 23, 1961; Dec. 21, 1961], No. 6011/62. Heading H2B. A limit switch assembly 10 includes a switch unit 12 and an actuator arm 20 mounted on a supporting frame 32, the frame being movable relative to one or more abutment surfaces 35T such that when a solenoid 62 is energized arm 20 moves into actuating alignment with a surface 35T and, when a portion of the arm 20 strikes the surface, the arm pivots and the switch 12 is operated. On de-energization of solenoid 62 a spring 64 moves arm 20 out of alignment. The actuator arm is connected to the solenoid armature 62c or itself forms the armature of the solenoid (Figs. 8, 9, not shown). Frame 32 carries a load (not shown) and is driven by a motor (not shown) with a circuit through closed contacts in the switch unit 12, the motor being stopped when the switch is operated by arm 20, e.g. so that the frame 32 halts at a selected shelf 35 on to which the load is to be transferred.
