ABSTRACT:
A dual-in-line switch package having a plurality of momentary contact switching stations and a plurality of indicating lights is disclosed. The switching mechanism of the switches is provided by a close wound coil spring having one end that encloses one contact and another end that is bent by the depression of a pushbutton so that it makes contact with a second contact in order to complete the circuit. The indicating lights may be light-emitting diodes which have lead extensions that are brought out of the package in line with the contacts for the switches. The light-emitting diodes rest on a support guide rail and are held in place in the switch when the cover is snapped on.
