Abstract
An electrical switch including a switch housing, a switch circuit disposed within the switch housing. The switch circuit including includes a movable contact member mounted on a contact lever and a stationary contact member. The contact lever is configured for operable-interaction with an actuator. The actuator is configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement in to the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement in to the second configuration whereby the switch circuit is closed.
Claims24
An attachment member for a contact lever of an electrical switch, the electrical switch including:
- a switch housing;
- a switch circuit disposed within the switch housing, said switch circuit including a movable contact member mounted on a contact lever and a stationary contact member, wherein said contact lever is movable between at least one of a first configuration in which the movable contact member is not in contact with the stationary contact member so as to open the switch circuit, and, a second configuration in which the movable contact member is in contact with the stationary contact member so as to close the switch circuit;
- said contact lever being configured for operable-interaction with an actuator, said actuator being configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement into the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement into the second configuration whereby the switch circuit is closed;
- and
- a biasing element configured for biasing the contact lever towards the second configuration so that the switch circuit is closed when the actuator is moved relative to the contact lever into the ON position, said biasing element including a first end attached to a first attachment point (A) in connection with a portion of the contact lever and a second end attached to a second attachment point (B) in connection with the switch housing;
- wherein, the attachment member comprises a first attachment member and a second attachment member, said first attachment member being configured for attachment with the contact lever and whereby said first attachment member is configured to provide the first attachment point for attachment with the first end of the biasing element, and said second attachment member being configured for mounting to the switch housing and spaced apart from the first attachment member, and whereby said second attachment member is configured to provide the second attachment point for attachment with the second end of the biasing element;
- and
- whereby said first and second attachment members include at least one of a plastic material, a rubber material, and a polymeric material, and are configured to alleviate vibratory movement of the contact lever when it moves the movable contact member into contact with the stationary contact member.

A contact lever assembly for use with an electrical switch, the electrical switch including:
- a switch housing;
- a switch circuit disposed within the switch housing, said switch circuit including a stationary contact member mounted within the switch housing and a movable contact member mounted on a contact lever of the contact lever assembly, wherein said contact lever is movable between at least one of a first configuration in which the movable contact member is not in contact with the stationary contact member so as to open the switch circuit, and, a second configuration in which the movable contact member is in contact with the stationary contact member so as to close the switch circuit;
- said contact lever being configured for operable-interaction with an actuator, said actuator being configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement into the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement into the second configuration whereby the switch circuit is closed;
- and
- a biasing element configured for biasing the contact lever towards the second configuration so that the switch circuit is closed when the actuator is moved relative to the contact lever in to into the ON position, said biasing element including a first end attached to a first attachment point (A) in connection with a portion of the contact lever and a second end attached to a second attachment point (B) in connection with the switch housing;
- wherein, said contact lever assembly includes an attachment member configured for attachment with the contact lever,
- whereby when attached to the contact lever, said attachment member is configured for operation as the first attachment point in connection with the portion of the contact lever, and whereby said attachment member is configured to alleviate vibratory movement of the contact lever when it moves the movable contact member into contact with the stationary contact member;
- and
- wherein, said attachment member comprises a first attachment member and a second attachment member, said first attachment member being configured for attachment with the contact lever so as to provide the first attachment point for the first end of the biasing element, and said second attachment member being configured for mounting to the switch housing and spaced apart from the first attachment member such that the second attachment member is configured for providing the second attachment point for attachment with the second end of the biasing element;
- and
- whereby said first and second attachment members include at least one of a plastic material, a rubber material, and a polymeric material, and are configured to alleviate vibratory movement of the contact lever when it moves the movable contact member into contact with the stationary contact member.
