Abstract

819,940. Retractive switches. ELEKTROSCHALTGERATE DRESDEN VEB. March 8, 1957, No. 7751/57. Class 38 (5). In a limit switch the contacts 2-5, the actuating push rod 13 and the terminals 6-9 lie approximately in a plane which is perpendicular to the plane in which the switch is secured, the direction of movement of the push rod being parallel to this latter plane. The switch is secured by bolts passing through the fixing holes 31, 32 and, as shown in Fig. 2, the switch base is contoured so that adjacent switches interengage. The moving contacts 14, 15 are urged apart by a spring 16 and abut C-springs 19, 20 engaging in slots 21-28 in the sleeve 12 attached to the push rod so that the position of a contact relative to the push rod can be varied by removing the appropriate C-spring and replacing it in another slot. Various arrangements of a number of switches on a bar are described, Figs. 9-13 (not shown).
