1.1.1 El tipo IST saca datos switchs del aislador se diseña proporcionar a un liso,
Lightweight action requiring minimum maintenance.

1.1.2 The complete operating mechanism parts are sufficiently
Insolated from live parts, and grounded for the safety of the operator.
The operating mechanism shall be of robust, adjustable design with padlock facility in either the “OPEN” and “CLOSE” positions.

1.1.3 The complete operating mechanism are comed complete with an
Operating handle and shall be designed for steady manual operation
From ground level.

1.1.4 The insulation for the operating mechanism handle are sufficient
For the safety of the operations and preferably incorporated with an
Anti - slip grip.

1.1.5 The vertical drive rod is suitable length and shall be provided
With facilities to extend or reduce the length. Suitable couplings and operating rod guides shall be supplied with each operating mechanism.
