20A Industrial Rotary Switch with 5 Cams and 3 Positions
The D505/5 rotary switch with 1-0-2 configuration is the professional solution for safe control of industrial equipment up to 4kW. With 10 contact pairs and robust construction, it ensures reliable switching between two separate electrical circuits, ideal for machinery, motors, and production lines. The visible lever with 3 clear positions guarantees safe operation and intuitive control.
What you get with this product
- Precise control between 2 separate circuits with a safe neutral position (0) that completely cuts off power
- Industrial capacity of 20A at 660V, sufficient for motors and equipment up to 4kW
- Guaranteed reliability for a minimum of 1,000,000 switching cycles, withstands intensive daily use
- Simple installation in electrical panels via 51mm diameter cutout, no special tools required
- IP42 protection after mounting against dust and splashes, suitable for industrial environments
- 10 contact pairs allow simultaneous connection of multiple control and power circuits
How it works and how to install it
The switch operates by rotating the red lever between 3 positions: 1 (active circuit), 0 (neutral - all circuits interrupted), and 2 (alternative circuit active). Each position activates or deactivates certain pairs of the 10 contacts, according to the cam diagram. Installation requires cutting a 51mm hole in the electrical panel, inserting the switch, and securing it with the included nut. Electrical connections are made via screw terminals, clearly marked according to the product label diagram. We recommend verifying the contact configuration with a multimeter before final connection.
Frequently Asked Questions
What does the 1-0-2 configuration mean and how do I use it?
The 1-0-2 configuration means you have 3 lever positions: position 1 powers the first circuit, position 0 cuts everything off (safety), and position 2 powers the second circuit. It is ideal for switching between two sources or two operating modes of a machine.
Can I use the switch for voltages lower than 660V?
Yes, the nominal voltage of 660V is the maximum permissible value. You can use the switch at any lower voltage (220V, 380V, 400V) without problems, the current capacity remaining 20A.
What do 5 cams and 10 contact pairs mean?
The 5 cams are the internal discs that operate the electrical contacts. The 10 contact pairs (20 terminals in total) allow you to simultaneously control multiple circuits with a single movement of the lever, useful for complex automation.
