Abstract
An electric switch of the normally closed type has a housing including a lower part that supports a fixed contact track, an internal contact blade that is resiliently deformable in order to assume a bottom rest position in order to establish an electric switching way, a first high non-stable position, in which the switching track is interrupted, and a second high stable position, in which the electric switching track is interrupted and in which the internal contact blade is locked such as by retractable locking structure, and an actuator to control the deformations of the internal contact blade.
Claims15
A normally closed electric switch comprising:
- a housing comprising an upper part made of insulating material and a complementary lower part that supports a fixed internal contact track;
- an internal contact blade that is supported by the upper part and that is resiliently deformable in order to assume:
- a bottom rest position, in which the internal contact blade is in downwards resilient abutment on the fixed internal contact track in order to establish an electric switching way, a first high non-stable position, in which the electric switching way is interrupted, and a second high stable position, in which the electric switching way is interrupted and in which the internal contact blade is locked by a retractable lock;
- an actuator to control the deformation of the internal contact blade, wherein the actuator, is pivotably mounted about a horizontal pivot axis, between:
- a first angular actuating position, in which the internal contact blade is in its first high non-stable position, and a second angular actuating position, in which the internal contact blade is in its second high stable position.
