Abstract

1392709 Retractive switches BURGESS MICRO SWITCH CO Ltd 31 July 1972 [3 Aug 1971] 36475/71 Heading H1N A snap-action switch comprises a housing 2 containing a contact arm 14, a resiliently flexible conductive actuator member 18 having a fixed portion 18b mounted in the housing and a displaceable portion 18a, the contact arm 14 being pivotally supported on portion 18a for displacement therewith and an over-centre spring 24 holding the arm 14 against the actuator member so that it engages and disengages at least one fixed contact 4 or 6 with a snap-action movement on flexure of the actuator member 18, the fixed portion 18b being held by frictional engagement with adjacent parts 40, 41 of the switch and being urged against a conductive member 8 to make electrical connection therewith. As shown two legs 20 are cut and turned down to carry arm 14 in slots 22, and a remaining tongue 30 is acted on by a button 32. The end 18b is bent at 34a and 34b to pass through an aperture 36 in terminal 8 with a knife-edge tip 38 pressing into a silver inlay 44.
