Zusammenfassung:The switch, has a sleeve-type housing which is closed at one end and pref. enclosed by an outer sleeve. The housing is of insulating plastic, impervious to water, dust and other media in the ambient atmos., and is in two parts. One comprises part of the sleeve and the other comprises the remainder of the sleeve portion with the end cover, where the two are sealed together by ultrasonic welding. At the end towards the 2nd part the 1st one is stepped to give a reduced external dia.. The 2nd part is slid over this portion until its end face butts against the annular face formed between this portion and the remainder of the peripheral surface, welding being carried out between the two faces. ADVANTAGE - Virtually excludes any misalignment between housing sections
