Abstract
A device for controlling the gas-burner rings of a cooking surface includes a gas tap equipped with a control knob and a catenary element for control of ignition of the gas-burner rings. The catenary element includes a microswitch actuated selectively by a bushing carried via snap action by an axially mobile element of the gas tap provided with the control knob. The bushing is made of a synthetic plastic material and includes a sleeve for installation on the mobile element of the gas tap and a flange configured to bear upon the microswitch to actuate it as a result of a motion of translation of the mobile element of the gas tap. The bushing is internally provided with a detent and has a radial slit, which interrupts its continuity and in a corresponding angular position of which the bushing is also provided with a pair of opposed circumferential slots that interrupt the continuity of the detent.
