Door unlatch switch assembly
First Claim
1. A switching apparatus for completing a circuit to actuate a latch, wherein the actuation of the latch is initiated in response to the completion of the circuit, the apparatus comprising:
- an elastomeric button;
a base supporting said button;
a leadframe supported by said base, electrically coupled to a control, and including at least one electrical contact;
an electrically conducting spring plate having a plurality of cantilever springs, said spring plate operatively disposed intermediate said button and said leadframe;
wherein the depression of said button causes said spring plate to come into contact with said at least one electrical contact to complete the circuit and initiate actuation of the latch.

Abstract
A switching apparatus and electromechanical latching system includes an elastomeric button with independently movable electrically conducting spring plates mounted to the button. The button includes a button cap including a relatively high durometer material and button walls including a relatively low durometer button material, such that the button walls collapse and the button cap generally maintains its shape when pressure is applied to the button cap. Each spring plate includes a plurality of cantilever springs. When the button is depressed, the cantilever springs of the spring plates come in contact with electrical tracks to complete a circuit. The completion of the circuit causes a signal to be sent to a vehicle computer, which signals a motor to release the automotive vehicle door latch.

8. An electromechanical latching system for an automotive vehicle door including a door latch, said system comprising:
-
a motor mounted in the vehicle door, said motor operationally releasing a door latch to allow the vehicle door to be opened;
a vehicle computer coupled to said motor, said computer controlling the operation of said motor; and
an electromechanical switch assembly coupled to said vehicle computer, wherein actuation of said switch assembly causes a signal to be sent to said vehicle computer causing said motor to release the door latch, the switch assembly including;
an elastomeric push button;
a base supporting said button;
at least two electrical tracks supported by said base; and
a conducting spring plate molded to said push button, said spring plate including independently movable cantilever springs, wherein said cantilever springs are movable to contact said electrical tracks to complete a circuit. - View Dependent Claims (9, 10, 11)
