Application
Rotary switches are used for controlling, automating and monitoring movements of a machine. These switches are used successfully as control switch on CNC machines, stamping machines, forging presses, sheet metal forming machines, welding machinery, machine tools, packaging machine, assembly machinery, transfer lines, transport equipment, lifts & elevators, Construction machinery, mining equipment, steel plants and in the off-road automobile industry.
Features & Specification
- Attractive Combination of colors for knob, Handle & Escutcheon plates.
- Silver alloy contacts used have a very high durability.
- Pad locking and lockable handles available for additional security and safety.
- A double break contact ensures positive making
- Cams used for contacting makes it suitable for switching in various programmable combinations.
- Modular design to achieve any number of poles wi.
Construction
This Switch is designed to operate electric motors and hence conforms to motor duty test for reversing and forwarding as well as inching of electric motor. They principally offer large number of possible switching combinations with consistent quality and reliability. They are modular in design with contact housing stacked with indexing mechanism. The operating knob is attached to steel shaft that rotates the cams which drive the contacts to an unlimited combinations of contact programs.
