Abstract

918,150. Key operated switches. ERICSSON TELEPHONES Ltd. July 27, 1961 [Oct. 1, 1960], No. 33762/60. Class 38 (5). A push-button assembly comprises two pushbuttons 1, 2 independently displaceable in a common walled slideway 3, each button having a stem 5, 6 occupying half the cross-sectional area of the slideway and being divided into two limbs by a central slot 11, one limb being extended to form a foot 12. The buttons are retained in the slideway by a rod 13 engaging slot 11. Each foot 12 engages two of three plungers 21, 22, 23, namely the spring-loaded centre one 22 and one other. Each plunger 21, 23 is slotted to slide over a rod 27 rigid with plunger 22. A latch (not shown) may retain the plunger 22 in its depressed position. When the latch is released plunger 22 rises with rod 27 pushing plunger 23 with it and push-button 1 is raised. Cam surfaces 31 on the plungers 21, 23 may operate spring blade contacts (not shown). Each push-button 1, 2 carries a label 10 inserted into a recess in its surface.
