On load switch disconnectors: it is switch disconnector that can open and close the circuit on load and perform the isolation required.
Off Load switch disconnectors: It is switch disconnector that must open and close the circuit when load is off (it can not operate on nominal load) – For example – Earthing switch used with CB during maintenance
The INS Switch is of the on load type
