Abstract
A selection switch is disclosed which is capable of accomplishing a clearly defined and smooth switching operation and contributing to the miniaturization of an apparatus such as a tape recorder. The switch includes a guide member for guiding a cassette of a tape by bending one of spring-biased contact members and a selector having a triangular projection outwardly projecting from the guide member wherein the triangular projection is backwardly pushed by the cassette while bending the other spring-biased contact member as a function of the shape of the cassette to actuate contacts of the contact members, to thereby select the deformation.
Claims5
A selection switch for identifying an object having a predetermined shape at a predetermined portion thereof, said switch comprising:
- an insulating base;
- at least two spring-biased contact members ebedded at a part thereof in said based so as to extend substantially in parallel with each other from said base;
- contacts respectively provided on said spring-biased contact members so as to oppose to each other with a predetermined constant relative position;
- a guide member having a guide surface of a predetermined width formed on a portion thereof and connected to one of said spring-biased contact members so as to allow said guide surface to slidably guide said predetermined portion of said object coming into contact therewith along a predetermined direction and to bend said one spring-biased contact member;
- means maintaining said predetermined relative position between said contacts during bending of said one contact member by said guide member;
- and
- a selector provided on the other of said spring-biased contact members, said selector being formed thereon with a triangular projection of which the upper portion is outwardly projected by a predetermined distance through and from said guide surface,
- wherein said triangular projection of said selector can be forcedly pushed to the position of said guide surface by said object contacting therewith while bending said other spring-biased contact member as a function of said predetermined shape of said object so as to change said predetermined relative position by the bending of said other spring-biased contact member, to thereby automatically detect said shape of said object.
