摘要：This disclosure depicts a novel multiple position electric pushbutton switch. Thenovel switch comprises a cam and a movable contact assembly having at least two springelements, each having an electrical contact and a cam-engaging portion. The switchfurther comprises at least two stationary electrical contacts for contacting the electricalcontacts of the movable contact assembly. A housing is provided for containing the cam,the movable contact assembly and the stationary contacts. As the cam is depressed andmoved downward into the housing, the cam engages one of the spring elements of themovable contact assembly causing the electrical contact on the spring element tocontact a corresponding stationary electrical contact. As the cam is depressed furtherinto the housing, the cam engages a second spring element causing the electrical contacton the second spring element to contact a corresponding stationary contact therebyresulting in a sequential connection of the electrical contacts as the cam is depressedinto the housing.
