Abstract

1463467 Mechanical switches SEB SA 25 Feb 1975 [20 March 1974] 7871/75 Heading H1N [Also in Division F1] A switch for an electric fan is operated by a control button which may be a push button 19 retained by tongues 50 with bent ends 21 which engage an annular rib 22, the switch 20 comprising a base 25 held resiliently against rib 22 by a tongue 28 integral therewith which abuts button 19 and which operates a ratchet comprising a pawl 34 and toothed cylinder 30 bearing a triangular end piece 31. Electric contacts 32, 33 which control a motor 10 are alternately opened and closed by rotation of triangular pieces 31 caused by pressure on button 19 to stop and start the fan. A second end piece 31 may engage another set of contacts to provide the fan with a second speed.
