Abstract
This electrical switch (1) consists of a flat spring, profiled in order to provide both a contact function and a spring function; the flat spring (1) includes a first leg (2) which can be deformed by bearing on a fixed pivot pin (3) of a support (4), and a second leg (5), which can move at the same time as the first leg deforms and whose end (5a) can assume either of two positions for contacting pins (14,15) of an electrical circuit. The switch according to the invention is less bulky than the usual switches by virtue of its flat shape, less expensive to manufacture, because it only consists of a single component, and easy to install on its support.
Claims10
An electrical switch (1;
- 16) comprising a support (4) having at least one fixed contact, a fixed pivot pin (3) and a fixed stop mounted thereon (11), and at least one flat spring (1) which is able to provide both a contact function and a spring function with respect to said fixed contact, said spring (1) including a first leg (2;
- 18) which is deformable by bearing on said fixed pivot pin (3) of said support (4) and having a first end fixed to said pivot pin and a second end, said spring (1) further including a second leg having a first end extending from said second end of said first leg (5;
- 17) which is movable with the first leg (2;
- 18), said second leg (5;
- 17) having a second end (5a;
- 17a) that can assume at least first and second positions with respect to said first contact, said second leg (5) further having a longitudinal hump (9) defined by a thickened section thereof in bearing contact against said fixed stop (11) and pivotable about said fixed stop (11) when initial movement of said second leg (5) occurs between said first and second positions in response to movement of said first leg, said longitudinal hump (9) further having an inclined end ramp (9a) slidable on said fixed stop (11) during subsequent movement of the second leg (5) between said first and second positions.
