Abstract
484,162. Actuation of switches. COOPER, B. S., and BLUSTON, L. Oct. 29, 1936, No. 29403. [Class 38 (v)] A switch comprises a thin silver wire contact 4 suspended from a conductor 8 and having its lower end passed through a loop in a wire 3 connected to the centre of a diaphragm 2. When sound waves enter a grille 15 the diaphragm vibrates and contact is interrupted at 3, 4 to energize an alarm circuit.
