Abstract

407,421. Hand actuating-devices for switches ; wireless receiving - sets. COREY, PARSONS, & CO., Ltd., SAYER, D. W., and ROE, J. E. M., Sumner Road, Peckham, London. Sept. 30, 1932, No. 27213. [Class 38 (v).] A number of tumbler switches are operated by rotary and axial movements of a spindle. The device is applicable to radio apparatus and in the form shown, a potentiometer or volume control device 4, a tumbler switch 12 for making and breaking the circuit to the receiver and a tumbler switch 13 for operating a change over from radio to gramophone reproduction are operated by the spindle which is in two parts 2, 3 slidable over each other, a pin 7 on the part 3 engaging a slot 6 in a sleeve portion 5 of the part 2 to ensure that the parts 2, 3 rotate together. The switches 4, 12 are operated by rotary movement of the spindle 2, a projection on a collar 10 on the spindle 3 engaging a slot 121 in the dolly of the switch 12 to operate it at the requisite time. The switch 13 is operated by axial movement of the spindle, a disc 11 on it engaging a slot 13<1> in the dolly of the switch 13. Other switches may also be operated by movement of the spindle.
