Abstract:
A press switch for controlling at least two functions in response to respective pressure exerted on the switch, comprising:an insulating substance having at least first and second conductive zones respectfully suitable for trigging first and second functions, at least the first conductive zone having at least two portions that are eletrically insulated from each other, the first portion being connected to an inlet track and the second portion being connected to an outlet track, the second conductive zone also being connected to at least one additional outlet track; a single having at least first and contact zones suitable for making contact respectively with the first and second conductive zones as a function of pressure exerted on the spring, the first contact zone having at least two regions that are electrically interconnected and suitable for making contact with respective portions so as to interconnect the inlet and outlet tracks, wherein each region forms a portion of a tab projecting from a free edge of said spring; the spring being positionable in at least three positions: a rest position in which it is in contact with part of at least the first conductive zone, the inlet track being connected to none of the outlet tracks and no function being performed; a first actuated position in which a first amount of pressure causes a connection to be established between the inlet track and the outlet tracks of the first conductive zone, said first actuated position being for triggering performance of the first function; and a second actuated position in which a second amount of pressure, greater than the first, causes contact to be established between each contact zone with the corresponding conductive zone, said second actuated position being for triggering performance of the second function.
