Abstract

1,018,910. Retractive switches. OLYMPIA WERKE A.G. Oct. 30, 1963 [Nov. 7, 1962], No. 42840/63. Heading H2B. A push-button operated switch for use in electric typewriters, for example, comprises an insulating body 1 of U-shape having lugs 2 which pass through slots in a mounting plate (not shown) and are retained by a wire spring clip 14 engaging slots 2<SP>1</SP> as shown. The clip 14 also passes through a slot 6<SP>11</SP> in a reciprocable member 6, thus resiliently limiting the travel thereof in each direction. Member 6 carries a button 15 and a contact spring 11 in the shape of an inverted W which bridges two fixed contacts 9 when the button is depressed.. A spring 8 provides retraction. The contact 11 straddles an insulating moulding 10 on member 6 and is normally held against shoulders 10<SP>1</SP> by a pin 12. The lugs 2 are arranged obliquely to the body 1 so that a plurality of switches may be mounted in close proximity without interference between the clips 14 (Fig. 4, not shown). The mounting plate may be stepped to carry switches in rows at different levels, or it may be inclined (as indicated by broken lines in Fig. 2, not shown), in which case the top of body 1 is made to slope correspondingly.
