About The Albright ED402 Stop Switches
The ED402 is a manually operated device with an over-centre spring mechanism which provides a snap action for both opening and closing of the main contacts. The ED402 is easy to install and is secured with supplied M5 Posidrive mounting screws. The ED402 is fully serviceable with genuine replacement parts available.
| Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). |
Precautions
The switch is to be used to rupture current in an emergency or as a no-load isolator.
The Use of Battery Disconnecting Switches in Electric Vehicles
Modern battery-powered electric vehicles are inherently very reliable and safe. However, even when sophisticated electronic controllers are used it is desirable to have a means of disconnecting the battery in the event of an emergency, such as a vehicle failing to stop or an electrical short circuit.
In many countries, it is mandatory to fit one or more devices to achieve an emergency disconnection of the battery.
