A gas regulating fitting that ensures simple manual operation is to be created. In particular, the device is to be capable of being switched both on and off in one operation. To that end, a microswitch (12) connected to an electronic control unit is arranged on the housing (1). The microswitch is operated when a tappet (10) arranged axially to the safety pilot valve (26) and the main valve (19) is manually operated. The electronic control unit thereby receives an electrical signal whereby the gas regulating fitting is activated in its switched-off state, and the gas flow flowing through the open safety pilot valve (26) is therefore ignited, whereas the holding current flowing to the thermoelectric safety pilot valve (26) is interrupted in the switched-on state of the gas regulating fitting, and the gas regulating fitting is therefore deactivated. The gas regulating fitting can be used to ignite and regulate a gas flow flowing to a burner.
