Abstract
A laminated electrical switch includes an insulative substrate having a lower stamped metal circuit sheet supported thereon. The lower sheet includes a plurality of switch contacts and a plurality of leads for connecting the switch contacts to appropriate conductors. An upper stamped metal sheet is disposed over the insulative substrate and includes a plurality of embossed metal domes in registry with and spaced from respective ones of the switch contacts. Depression of a selected one of the embossed metal domes engages the dome with a respective one of the switch contacts to close a circuit therethrough.

A laminated electrical switch, comprising:
- an insulative substrate;
- a lower stamped metal circuit sheet supported on the insulative substrate and including a common contact, a plurality of switch contacts and a plurality of leads for connecting the common contact and the switch contacts to appropriate conductors;
- and
- an upper stamped metal sheet disposed over the insulative substrate in engagement with the common contact of the lower stamped metal circuit sheet and including a plurality of embossed metal domes in registry with and spaced from respective ones of the switch contacts, whereby depression of a selected one of the embossed metal domes engages the dome with a respective one of the switch contacts to close a circuit between the common contact and the respective one of the switch contacts.
A laminated electrical switch, comprising:
- an insulative substrate;
- a lower stamped metal circuit sheet insert molded in the insulative substrate and including a common contact and a plurality of switch contacts with a plurality of leads for connecting the common contact and the switch contacts to appropriate conductors;
- and
- an upper stamped metal sheet disposed over the insulative substrate and including a portion in engagement with the common contact of the lower stamped metal circuit sheet and a plurality of embossed metal domes in registry with and spaced from respective ones of the switch contacts, whereby depression of a selected one of the embossed metal domes engages the dome with a respective one of the switch contacts to close a circuit through the respective switch contact and the common contact.
