Light sensitive switch is a device that is used for automatically switching on and off the street lights garden lighting, passage lighting and doorway lighting etc in accordance with the natural lighting level.
The lights connected to the light sensitive switch are turned on automatically in evening when the natural light falls below 15 lux. And lights are switched off in the morning automatically when the light level reaches above 20 lux.
Eliminates the need of human operation for switching on and off any external light connected with this system.
Saves energy saves electricity , no need to manually switching on and off the light, easy to install and durable.
Applications: roadway lighting , building perimeter lighting , outdoor advertising signs , parking lot lighting, garden lighting passage lighting and doorway lighting etc.
MCC-F load cell uses the beam structure ,the high accuracy, low contour, sealed , stable performance; has strongly anti-torsion, anti-side ability, is suitable in electronic weighing apparatus and so on for automobile scale, track scale, platform scale, bunker scale, crane, and compression testing machine.
