According to the invention, the arrangement is such that the switch is hermetically sealed.

According to the invention is also provided that the electric Sehalter has a new and improved diaphragm, which has a particular advantage in The kit has hermetically sealed miniature switches

The inventive switch is also not hawser only in its (small and hermetically sealed, but precisely in its operation, simple in construction and economical to manufacture · "Ββχώμτ he can be easily calibrated his ropes can be mass produced and securely assembled quickly xm & and be kept in a calibrated position «, In the drawing Ausftthrungebebeispiele the invention are shown _o Eb show:
