Switching device for pneumatic instruments - has toggle switch with manually operated pushbutton and indicator in front plate

摘要

Switching de ice especially for pneumatic conducting instruments for switching over from hand control to automatic where there is a switch and an indicator for the switch position. Specifically, the switch serves as a toggle switch (13a, 13b, 13c, 13d) which, with a manually operated pushbutton, projects outwards through a cut out (11) in a front plate (10) of the system. The switch has two side extensions (14a-14d, 15a-15d) behind the front plate, with markings (16, 17) to indicate the appropriate switch position. Further, the toggle switch is so supported behind the front plate that the cut out in the front plate is so covered in each switch position by one or both sides extensions that the marking is visible in the recess to indicate the switch position.
