The cam switch can be defined as a set of contacts predisposed to interrupt and connect logical circuits in a specific order.
The rotary movement of the cams, which function to open / close the contacts, allow to perform multiple electrical functions controlled by a single operation.
The Rotec cam switches are suitable for both DC and AC in and are designed and manufactured in accordance with international product standards IEC 60947-1, IEC 60947-3, UL508, CSA 22.1-14 and also satisfies the requirements of Directive 2004/108 / EC relating to electromagnetic compatibility.
The active parts of the switches i.e. contacts are double break silver alloy contacts; plastic materials have high mechanical strength and resistance surface currents.
The wide range of product, from 12A to 315A (AC 21A), the number of positions, the different angles for maneuver which can be supplied (30°,45°,60°, 45/90°, 90°) and the vast assortment of switching devices and accessories, allow the creation of a wide range of customer-specific solutions and of course the typical applications of the product i.e. switches, changeover switches, reversing switches, Dahalander switches, star delta switches and multi-step switches.
To complete and integrate the switches, the Rotec Series also includes control switches, made up of a very wide range of control and signaling units that meet multiple solutions for use in the command and control of electrical circuits, low-voltage DC powered and AC powered: pushbuttons, illuminated pushbuttons, emergency pushbuttons, key and knob handle selector switches, illuminated selectors, joystick operators, pilot lights, and a wide range of accessories.
The control switch operators are manufactured and designed in accordance with product standards IEC 60947-5 with particular reference to the safety requirements of the European Machinery Directive EN60418.
The contact elements are in compliance with the product standard IEC 60947-5, UL508 and CSA 22.1-14 and are connectable and lock coupled (snap on system) ensuring the viability in the wiring of any diagram function; are also wireable separately by simplifying installation and maintenance.
The control switches are manufactured in two basic lines: 22 mm diameter body with metal or plastic in round or square version and 30 mm diameter and are all with protection IP65.
The constituent parts of the product provide excellent thermal characteristics, dielectric and mechanical and therefore the reliability and safety of operation, such as the pads silver alloy with double interruption of the contact elements.
