Abstract

677,001. Mechanical switches without quick action. NEALE & SONS, Ltd., J., and NEALE, M. R. June 26, 1950. [June 25, 1949] No. 16896/49. Class 38 (v). [Also in Group XI] A switch for controlling an electric inspection lamp incorporating an electromagnet for attaching it to a magnetisable surface comprises a button 12 mounted on a spring plate 20 and having a recess 19 engaged by one end of a bell crank lever 8 mounted on a pivot 9 on an insulating disc 10. On moving the button in a slot 21 in the lamp casing 1 the arm 22 of the bell crank is moved into or out of contact with a fixed contact 13 to complete or break the circuit.
