ABSTRACT:
An electrical switch housing which may be mounted on the control shaft of a gas valve of a household gas appliance in order to control an ignition circuit which ignites the gas that is controlled by the valve is provided. The electrical switch housing has a central aperture which holds a rotatable operating member that has an aperture in it which receives the control shaft of the valve. The switch housing may have two, three or four mounting posts which extend normal to it and are positioned relative to one another so that they prevent the housing of the switch from rotating when the control shaft is rotated.
