FIG. 1 shows the safety release holder in its notched position or in its first position. The contact tracer 45 is released and, under the action of the force of the spring 54, has moved upwards into its first position.

Due to the U-shape of the contact spring 59, a very slight pressure exerted on the button 71 also causes the contact spring 59 to be pulled inwards, so that the ends 61 and 62 are pulled inwards away from the contacts 52 and 53 created, which prevents an old the anochromes 50 and 51 connected control circuits is closed if the button is held in any way in the lower position. If, for example, aer button 71 is stuck in its lower position, the contact spring 59 closes Circuit between the connections 50 and 51 not even if the contact gate 45 is in a two-tone or locked position (β Figure 4)
