Abstract

1369897 Mechanical switches CHERRY ELECTRICAL PRODUCTS CORP 9 Nov 1972 51739/72 Heading H1N In a push-button switch, movable spring blade contacts 29, Fig. 2, normally urged into yielding engagement with fixed contact blades 24 are restrained to the open-circuit position by cams 46 on a trapezontal members 44 forming part of a reciprocally movable actuator assembly 36, 40, 44. In operation the cams 46 normally engage internal lugs 34 extending on opposite side edges of the spring blade contacts 29 but on depression of the actuator 40 the lugs 34 are released to permit a contact portion 35 on the blade 29 to engage a corresponding contact portion 27 arranged at right angles thereto to provide point contact on the fixed contact blade 24. The contacts 24, 29 have base portions with barbs (32), Fig. 6 (not shown), for rigid engagement in slots, the base 12 through which terminal lugs 30 extend. Lugs 28 on the other end of each fixed contact 24 are located in recesses on the top wall 22 of the housing 11. Projections 48 on the actuator assembly engage guide slots (19), Fig. 9 (not shown), in the housing 11. In a modification the cam edges may have slots 31, Fig. 10, engageable with the lugs 34 to momentarily resist initial movement of the actuator assembly and thereby provide a tactile feel.
