Keyswitch

A keyswitch comprising a housing having a bottom wall and an open upper end, a plunger having a tubular body extending downwardly in the housing and slidably engaging said housing for movement up and down therein, means limiting upward travel of the plunger to a predetermined elevated position, the lower end of said body being spaced above said bottom wall while the plunger is in said elevated position, said bottom wall being provided with a pair of laterally spaced openings extending substantially vertically therethrough, a pair of opposed spring contact strips mounted in said openings and projecting below said wall to form terminals, said contact strips also converging upwardly inside the plunger and having normally engaging upper ends, a cross member inside the plunger body and supported thereby between the contact strips, and a coil spring inside the plunger below said cross member and encircling the contact strips but spaced therefrom, said spring normally holding the plunger in said elevated position with said cross member spreading the upper ends of the contacts apart, said downward movement of the plunger in said housing disengaging said cross member from the contacts, and said contact strips being substantially identical and each having at least two parallel slits extending downwardly from its upper end to form a plurality of laterally spaced narrow contact fingers at one side of a wider contact finger wide enough to be engaged by the narrow contact fingers of the other contact strip when said cross member is disengaged from the contact strips.
