Our Change Over Switches (Knife Type) find applications in industries and commercial establishments where individual mounting of switches is required.

Applications Rotary knife switches are mudular & compact in design and are very versatile for switching a.c. as well as d.c. resistive & inductive loads. They are used as Control switches in Control Panels and equipments such as MV & HV - Vaccum Circuit Breakers, Gas Circuit Breakers, On Load Tap Changers and Motor control panels. The switches are used as Mains switch or for instrument selector i.e. Ammeter selector & Voltmeter selector switches. These switches offer advantage of having quick make and break contacts for on load d.c. applications. Features:  Knife type of contacting making it suitable for switching on load d.c.  Self cleaning of contacts is done during the operation.  Modular design to achieve any number of poles with minimum components.  Specially designed operator independent quick make/break mechanism.  Superior insulating material ensures electricals & mechanical stability. Specification:  Conventional free AIr Thermal Current Rating (lth):16 Amp.  Operational Voltage: 220 volts d.c.  Operational Current: 6 Amp.  Utilisation Category: DC13  Switching capacity: Inductive loads with L/R ratio (time constant) of 20mS  Dielectric Strength: 2.0 kv for 1 minute  Insulation Resistance: > 500 Mohm  Mechanical Durability: > 5,00,000 operations  Electrical Durability: > 100,000 operations

A knife switch controls the flow of electricity in a circuit & is widely used electrical experiments. It has a hinge that lets a metal lever, or knife, be lifted from or placed in into a slot. The hinge and jaw are affixed to an insulated base, and the knife has an insulated handgrip to hold it.
