Such a push button combination is known and in the

German patent specification .. ■> ·. ₀ (patent application J 27 957

™ locked state indicates the off position of the device » while the other push button is used to activate the ignition safety device. When an ignition safety device is started up, it must be reliably prevented that the gas supply is first released and any failure to ignite. The gas that has flowed out at the burner can then be attempted immediately afterwards a further ignition process with renewed release of the gas supply to the burner, since ee aui in this way can lead to deflagration of the oasis flowing out,

| i Rather, there is a requirement that swipohen a first give the gas supply and sins of the leaked gases * and every further release of the gas supply, a purging time is observed in order to avoid deflagration o this requirement after compliance with a flushing tent, the well-known pressure test combination is fully sufficient due to the locking slide attached to it Scope. _ ·

A preferred embodiment provides that a through dae Locking mechanism caused the operating button to be locked. can be released by the ignition safety valve when it passes into its closed position «■

In detail, the arrangement is made such that the valve body of the flap valve is attached to a leg belonging to an angle lever, which is arranged approximately parallel to the push rod of the off-I ¹ as te and is directed approximately towards the off button The apex line is pivotably mounted and the other leg is directed transversely to the pressure direction of the pressure ram, through which the valve body can be pivoted via a driver guided on the pressure ram, which acts on the transversely directed leg of the angle lever ο The driver acts as the pressure tappet the Aus-Tas-fce displaceable hollow piston is formed, at the end of which is directed towards the Off button at least one radially protruding

the and on the transversely directed leg of the angle lever to the action of coming cams is provided while inside of the hollow piston a compression spring encompassing the pressure tappet is arranged is, which on the one hand against the bottom surface of the hollow piston and on the other hand against one on the pressure tappet inside the ring shoulder attached to the hollow piston is clamped the free end of the leg of the angle lever connected to the valve body of the flap valve is a resilient one Assigned locking lever, which the valve body in its open position e.g. locked by means of a locking lug.

In addition, the further development consists in the fact that the pressure ram of the discharge has such a length that the free end of the pressure ram hits an extension of the locking lever when the off button is fully pressed and the locking of the valve body is released At the end of the plunger of the Aus-Iasts, a driving ring disk is blown in, which when the locked Aus-Saste is released by pressing the operating state of the driving hollow piston in the direction of the OFF button, so that the qusr üsrichteto leg of the angle lever is released; ^i! : t v-ird-and iier YanirJUbody des

In order to ensure compliance with a flushing time mentioned at the beginning, the operating button 25 must only be able to be pressed when the off button 35 is in a locked position assumes, so that the off button 35 must first be released before the operating button 25 can be pressed. To this The purpose is a cover 101 of the housing 10 along the displacement paths of the two pushbuttons 35 and 25, a locking slide 40 (see in particular FIGS. 2, 5 and 10) is attached} which

against the action of a compression spring 41 (FIGS. 2 and 7) can be moved transversely to the direction of displacement of the two pushbuttons 35 and 25. The locking slide 4-0 has an opening and locking cam 42 assigned to the off = button 35 with a detent 43 and a locking and opening cam 44 assigned to the operating button 25 with a locking surface 45. Furthermore, an approximately trapezoidal projection 46 is attached to both the off button 35 and the operating button 25, which comes into operative connection when the respective pushbutton is pressed either with the opening and locking curve 42 or with the locking and opening curve 44 ₀ ™ Die The operation of the locking slide is described in detail in the German patent ............. ο ₀ c (patent application J 27 957 VIIId / 21 e). In this way, the operating button 25 of the thermoelectric ignition safety device can only be pressed when the off button 35 is in or has resumed its locked position. This means that after an unsuccessful ignition process, the operating button 25 cannot be easily pressed but that the off button 35 must first be brought into its locked position, ao that a flushing time is achieved by this measure on the burner.

Operating button 25 can be switched on, because otherwise gas coming to the outflow would ignite on the heated ceramic heater, which could result in a more or less violent deflagration. For this reason, a safety time must be observed between switching off the device by pressing the off button 35 and restarting it by pressing the operation button 25. This safety time, which is required for the previously heated ceramic heater to cool down sufficiently, essentially corresponds to the shutdown time the thermoelectric Zündsicherungs-Yorrichtung, d ^ h * that time which is required after the cessation üeg Beheizens of the thermocouple and thus "deep discharging of thermal power to the winding 12 of the electromagnet \ J> of the thermoelectric Zündeicherungsvorrichtung the drop of the anchor plate H by the electromagnet 13 to receive

In order to comply with this safety time, a lock has been created according to the invention which only enables the operation button 25 to be pressed when the device is fully operational before and after it has been switched off by pressing the Aue button when both the off button 35 is in its off position through the locking slide 40 -dtstellung locked and at the same time the ignition safety _{valve is closed, d «, h 0} the valve body 19 rests on the valve seat 20.
