A bobbin for an electrical coil is described having a main winding space for electrical wire and at least two separate further winding spaces for terminating the wire wound on the main winding space. The or each further winding space has a groove in which a number of terminating wire coils can be wrapped. The groove is breached or gapped so that the wire coils wrapped in the channel bridge the breach and can be wholly or partially soldered together at the bridging portions to form terminal connections to the wire on the main winding space.

1. A reed relay assembly, comprising: a bobbin having a hollow interior; first and second spaced apart flanges integrally formed on said bobbin for defining therebetween a first main winding space, at least one of said flanges having at least one slot for defining a wire passageway; third and fourth flanges integrally formed on said bobbin and axially spaced from said first and said second flanges for defining a second and a third annular termination winding space; a selected length of electrical wire wrapped a preselected number of turns around said first winding space to provide a main coil and wrapped a preselected number of turns around said second and said third annular termination winding spaces to provide termination windings the individual turns of which are electrically joined together to provide first and second electrical terminals for said main coil; and a reed switch disposed through said hollow interior and within said main coil. 2. The reed relay assembly of claim 1, wherein each of said third and fourth flanges are outwardly axially spaced from respective ones of said first and said second flanges and define said second and said third annular termination winding spaces respectively between said first and said third flanges and between said second and said fourth flanges, and wherein both of said first and said second flanges are provided with a slot. 3. The reed relay assembly of claim 1, wherein said third and said fourth spaced apart flanges are both axially spaced apart outwardly to one side of one of said first and said second flanges, and wherein said second annular termination winding space is formed between said fourth and said third flange, and said third annular termination winding space is defined between said one of said first and said second flanges and said third flange, and wherein said one of said first and said second flanges is provided with two spaced apart slots. 4. The reed relay assembly of claim 1 further including a fifth flange integral with said bobbin intermediate said first and said second flanges and having a fourth annular termination winding space whereon said wire is wrapped a preselected number of turns and the individual turns thereof are joined together electrically for providing a tap for said main coil. 5. The reed relay assembly of claim 2, wherein said third and said fourth flanges are truncated such that said annular termination winding spaces are in communication with said hollow interior. 6. The reed relay assembly of claim 3, wherein said third and said fourth flanges are truncated such that said annular termination winding spaces are in communication with said hollow interior. 7. The reed relay assembly of claim 1, further including a lead frame having a first pair of terminals adapted to electrically contact respective ones of said first and said second electrical terminals of the main coil, and a second pair of terminals adapted to electrically contact respective terminals of said reed switch. 8. The reed relay assembly of claim 1, further including a plastic material encapsulating said reed relay assembly. 9. A bobbin for an electrical coil, comprising: a bobbin having a hollow interior; first and second spaced apart flanges integrally formed on said bobbin for defining therebetween a first main winding space, at least one of said flanges having at least one slot for defining a wire passageway; third and fourth flanges integrally formed on said bobbin and axially spaced from said first and said second flanges for defining a second and a third annular termination winding space; a selected length of electrical wire wrapped a preselected number of turns around said first winding space to provide a main coil and wrapped a preselected number of turns around said second and said third annular termination winding spaces to provide termination windings the individual turns of which are electrically joined together to provide first and second electrical terminals for said main coil.
