Illuminated pushbutton switch with unitary spring and contact

摘要

An illuminated pushbutton switch has a translucent button aligned with a lamp, a stationary contact, and a sinuous spring urging the button to its released position, the spring being bifurcated and straddling the lamp to allow a clear illumination path. The spring serves as the movable contact of the switch and engages the stationary contact when the button is depressed.
