Title (EN) ELECTRIC SWITCH UTILIZING COIL SPRING TORSION BIASING IN SWITCH OPERATION
(FR) COMMUTATEUR ELECTRIQUE UTILISANT L"EFFORT DE TORSION D"UN RESSORT HELICOIDAL DANS LE FONCTIONNEMENT DU COMMUTATEUR
Abstract: front page image
(EN)A miniaturized electrical switch (10) particularly suitable for electronic keyboard control applications includes at least one coil spring (50) having a laterally extending end (52) with an end contact (54) where spring compression biases the switch toward an unoperated condition and spring torsion urges the first end contact (54) relative to a second contact and a switch housing mounted cam (62) engages the end contact (54) incident operation of the switch between operated and unoperated conditions to urge the end contact (54) relative to the second contact.
(FR)Un commutateur electrique miniaturise (10) se pretant particulierement a des applications de controle de clavier electronique, comprend au moins un ressort helicoidal (50) ayant une extremite s"etendant lateralement (52) avec un contact d"extremite (54), ou la compression du ressort rappelle le commutateur vers une position inoperante et la torsion du ressort force le premier contact d"extremite (54) sur a un second contact et une came (62) montee dans le bati du commutateur coopere avec le contact d"extremite (54), provoquant la mise en fonctionnement et hors circuit du commutateur pour forcer le contact d"extremite (54) sur le second contact.
