Abstract
The present invention concerns a portable object such as, in particular, a timepiece (1) including means for controlling at least an electronic function such as an horological function, these control means including at least a touch-sensitive key (16) for selecting the desired electronic function, characterized in that the control means further include a strain gauge (22) allowing the selection of the desired electronic function to be confirmed and/or the electronic function to be activated, the confirmation and/or activation of said electronic function being effected by applying pressure to the portable object via the effect of which the strain gauge (22) generates a control signal which will be applied to an electronic data processing circuit, said portable object also being able to include means able to emit an acoustic signal to indicate to a user that the desired function has actually been switched on.
