  • Patent number: 5187336
    Abstract: An electrical switch assembly operable by means of a force applied in a first direction and including a switch having an switch actuator member responsive to a force applied thereto in a second direction orthogonal to the first direction. The switch assembly further comprises a transfer actuator having a force receiving portion facing the first direction and an end portion flexibly connected at a first end thereof to the force receiving portion and at a second end thereof bearing against a surface slidably in the second direction. A tab connected to the end portion and movable therewith is operably aligned with the switch actuator member. A force applied in the first direction to the force receiving portion of the transfer actuator is transferred to the second direction to operate the switch. This is accomplished by means of the transfer actuator having a shape that flattens out when a force is applied thereto from the first direction.
