Features

Easy for installation and maintenance
1] Every facility is available for wiring , maintenance and fitting of cable boxes.
2] The terminals are suitable for aluminium & copper cables.
Quick make-and-break operation
Switches are provided with a spring assisted quick make-and-break operating mechanism to minimize arcing.
Low contact resistance
Besides providing liberal contact area, when copper contact blades meet brass terminals they are snugly held and constantly pressed against the smooth sides of the terminals.
This is insured in every unit by
1] Selection of brass terminals of correct composition and measurement.
2] Making contact blades of a special design formed from rolled electrolytic copper strip of accurate thickness. The round edge of contacts avoid sharpness and minimize sparking of contacts.
3] Specially designed phosphor bronze carrier springs enveloping the terminals to firmly grip the contact blades and press them against the terminals.
4] Assembling the terminals with the carrier springs on an accurate fixture so that there is no air gap between the copper contact blade and the terminal.
This is how the contact resistance is significantly reduced and thereby the rise in temperature is kept to the minimum level.
