BISTABLE ELECTRIC SWITCH WITH SHAPE MEMORY ACTUATOR |
| 摘要 |
A bistable electric switch is described. The switch has as actuators a pair of opposing SMA wires acting on a drive element integral with a snap-action spring so as to toggle the snap-action spring between two stable positions corresponding to two operating positions of the switch, the drive element being shorter than the distance existing between the two opposing SMA wires when one of the SMA wires is contracted and the other SMA wire is uncontracted. The entire force exerted by the activated SMA wire is used to overcome the resistance of the snap-action spring. |

1. A bistable electric switch comprising a pair of opposing shape memory alloy (SMA) wires acting on a drive element integral with a snap-action spring so as to toggle the snap-action spring between two stable positions corresponding to two operating positions of the switch, wherein said drive element is shorter than the distance existing between said opposing SMA wires when one of the SMA wires is contracted and the other SMA wire is uncontracted. |
