摘要：
The present invention relates to a three-position disconnector switch, comprising:
- an earthing contact (1);
- a power out contact (2);
- a power in contact (3);
- a first piston (4a); and
- a second piston (4b).
In a connected switch position: the first piston is configured to make an electrical connection with the power out contact and the second piston is configured to make an electrical connection with the power out contact and the power in contact;
In a disconnected switch position: the first piston is configured to make an electrical connection with the power out contact and the second piston is configured to make an electrical connection with the power out contact;
In an earthed switch position: the first piston is configured to make an electrical connection with the earthing contact and with the power out contact and the second piston is configured to make an electrical connection with the power out contact.
- an earthing contact (1);
- a power out contact (2);
- a power in contact (3);
- a first piston (4a); and
- a second piston (4b).
In a connected switch position: the first piston is configured to make an electrical connection with the power out contact and the second piston is configured to make an electrical connection with the power out contact and the power in contact;
In a disconnected switch position: the first piston is configured to make an electrical connection with the power out contact and the second piston is configured to make an electrical connection with the power out contact;
In an earthed switch position: the first piston is configured to make an electrical connection with the earthing contact and with the power out contact and the second piston is configured to make an electrical connection with the power out contact.
