Multi-Station Push Button Switch

摘要

A 2- and 10-station, mechanical-interlocked and sealed push-button switch assembly is being developed to have illumination and snap action also. Each station is to have as many as 6 double-pole, miniature switch circuits, a front removable lens and lamp unit, requiring no tools for removal, and all circuitry associated with the lamp and miniature switches. A counteracting mechanism was designed having the differential travel space required for the teaseproof function placed opposite the button, thereby putting all lock-out and actuating functions on the same side of the pivot. The button is then a floating member, serving only as a balancing means of transferring the button force applied through the pivot to the cone and actuator.
