Abstract

A switch assembly which has a mount (12), an elongate member (14), a switch (16) and a fulcrum (18). Pressing on elongate member (14) provides a force to actuate switch (16). Elongate member (14) is resilient or, alternatively, is resiliently biased to return to an unactuated position. Fulcrum (18) is movable along a length of elongate member (14). Positions of fulcrum (18) along the length enables variation of the force to actuate switch (16). As a result of this variation, different tactile feel of the switch assembly can be provided depending on position of fulcrum (18) relative to switch (16). Fulcrum (18) can also be positioned along elongate member (14) to provide a locking position that prevents switch (16) from being actuated.

Claims

1. A switch assembly comprising:

a mount;

an elongate member associated with said mount; and

a fulcrum, slidably coupled to said elongate member, said fulcrum being movable along a length of said elongate member such that positions of said fulcrum along said length varies a force on said elongate member to actuate a switch within said mount.

2. The switch assembly as claimed in claim 1 wherein said elongate member is resilient and coupled to said mount.

3. The switch assembly as claimed in claim 1 wherein said elongate member is resiliently biased and coupled to said mount.

4. The switch assembly as claimed in claim 1 wherein said elongate member comprises a mounted end and a free end, said fulcrum being movable between said mounted end and said free end.

5. The switch assembly as claimed in claim 4 wherein said switch is disposed between said free end and said fulcrum.

6. The switch assembly as claimed in claim 4 wherein said switch is disposed between said mounted end and said fulcrum.

7. The switch assembly as claimed in claim 1 wherein said elongate member comprises a protrusion for engaging said switch.

8. The switch assembly as claimed in claim 1 wherein said elongate member is integral with said mount.

9. The switch assembly as claimed in claim 1 wherein said mount comprises at least one stopper for enabling a locking position to prevent actuation of said switch when said fulcrum abuts said stopper.

10. The switch assembly as claimed in claim 1 wherein said mount is part of a housing for an electronic device.
