ABSTRACT:
A handle16for exterior use in a vehicle to authorize a mechanism (18) to unlatch an access door has a structural part (34); a cover (36); and a pair of sensors or switches (28, 29) between the structural part (34) and the cover (36). A first sensor or switch (28) to interact with one or more fingers of a user's (26) hand (2) and a second sensor or switch (29) spaced from said first sensor (28) to be activated by a user's (26) different finger or the user's (26) thumb. The combination of the two switches or sensors (28, 29) signal the mechanism (18) to unlatch the access door and wherein the activation of only the second sensor or switch (29) in the absence of touching the first sensor or switch (28) authorizes a mechanism (18) to lock the access door. Preferably, the first and second sensors or switches (28, 29) are electrically coupled such that activation of both authorizes an unlatching of the access door while the activation of only the second sensor or switch (29) authorizes a lock only feature. Accordingly, the second sensor or switch (29) changes authorization from unlatch to lock dependent on the use or non-use of the first sensor or switch (28).
