Rotary Switches - PCB Type - Series 35
OVERVIEW
Integral Series 35 Rotary Switch - PCB type is designed to be used directly in PC 0 0 Boards and switches 2 to 24 positions with 15 or 2-12 positions with 30 index angle.
It can be fixed in the PCB with the four soldering pins of the frame with only the shaft projecting from the panel. Alternately it can also be fixed on the front panel using the 3/8 x 32 TPI threaded bush and nut which is a part of the index mechanism. A maximum of ten dust proof switching modules with a maximum of 24 pairs of spring contacts can be mounted into a rigid frame. The soldering pins are sealed with epoxy resin or moulded so that during soldering no flux or other matter can enter the switching module.
FEATURES:
» Choice of 15 /30 index angle.
» Spacing between terminals 1 grid (2.54 mm).
» Provides protection against dust & adverse environmental condition.
» Epoxy sealing or moulding of terminals prevents flux flowing into contact.
» Life time lubrication of contacts.
» Gold plated moving contacts.
» Easy replacement of modules without disturbing the entire assembly.
» Max : 10 modules can be assembled in a single frame.
» Max : 24 terminals per module.
