    • A snap-action switch includes an M-blade snap spring, an actuation arm, a first bridge, and a second bridge. The M-blade snap spring includes a closed end, a double-loop end, a first outer leg, a second outer leg, a first inner leg, a second inner leg, and a cross member. The actuation arm is coupled to the first and second inner legs, and distorts the M-blade snap to exhibit snap-action movement between a first switch position and a second switch position. When the M-blade snap spring is in the first switch position, the double-loop end engages the first bridge and does not engage the second bridge, and when the M-blade snap spring is in the second switch position, the double-loop end engages the second bridge and does not engage the first bridge.
    • 快动开关包括M形刀片卡扣弹簧,致动臂,第一桥和第二桥。 M形刀片卡扣弹簧包括封闭端,双回路端,第一外腿,第二外腿,第一内腿,第二内腿和横梁。 所述致动臂联接到所述第一和第二内部支腿,并且扭曲所述M形刀片卡扣以在第一开关位置和第二开关位置之间呈现卡合动作。 当M型刀片卡扣弹簧处于第一开关位置时,双回路端部接合第一桥接件并且不接合第二桥接器,并且当M形刀片卡扣弹簧处于第二开关位置时,双回路 端部接合第二座桥,不接合第一座桥。

    • A low profile membrane switch adapted for use over an automobile steering wheel airbag assembly for actuating a horn. The low profile membrane switch is comprised of an opposing pair of flexible electrodes separated by a dielectric layer. The dielectric layer has a unique pattern defining opposing electrode contact portions. A plurality of integral outwardly-extending protrusions are screen printed on the exterior surface of each flexible electrode, one over each of the opposing contact portions. These protrusions help concentrate an applied force to bring the respective electrode contact portions together to make electrical contact with the other. The opposing contact portions are defined by the dielectric pattern, and have a high density to insure redundancy and closure of the switch when one depresses the membrane switch with one's hand, and to insure the switch does not inadvertently close when flexed. An applied force of as little as four pounds causes closure of the membrane switch, even when positioned over a resilient airbag device.
    • 一种适于在汽车方向盘安全气囊组件上使用以致动喇叭的薄型薄膜开关。 薄型薄膜开关由相对的一对由电介质层隔开的柔性电极构成。 电介质层具有限定相对电极接触部分的独特图案。 多个整体向外延伸的突起被丝网印刷在每个柔性电极的外表面上,一个在每个相对的接触部分之上。 这些突起有助于集中施加的力以使各个电极接触部分在一起以与另一个电接触。 相对的接触部分由电介质图案限定,并且当用手压住膜片开关时,具有高密度以确保开关的冗余和闭合,并且确保开关在弯曲时不会无意地闭合。 即使定位在弹性安全气囊装置上时,施加的力小至四磅也会导致膜开关闭合。
