Abstract
466,866. Actuation of switches. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and LINSELL, A. A. Dec. 3, 1935, No. 25355 /36. Divided out of 466,756, [Group XL]. [Class 38 (v)] [Also in Group XL] The handle SW2 of a selector in a television receiver moves in a T-shaped slot. When the handle is at the free end of the stem of the T, the receiver is switched off, at the other end the receiver is switched on except for circuits which determine the scanning-line frequency and the size of the scanning-spot, at one end of the head of the T circuits for one scanning-line frequency and one size of spot are completed, and at the other end circuits for another frequency and size are completed. A spring biasses the handle to the " off " position when in the stem of the T, Fig. 6 (not shown).
