Door Switch ( Reed Switch )
In certain applications a door contact sensor or switch may be connected to the temperature control system to control the internal evaporator fan.
Especially in cooling cabinets, stand alone freezers etc. there is limited space to locate a door switch.
Reed sensors are extremely reliable and durable; the life expectancy of the average reed switch is a minimum of 9 million switches.
The dimensions of a reed switch assermbly are small and the units are easy to fit in every possible application. The main limitation of the reed switch is the maximum Amperage it can switch .
