Regarding the miniature switch, it can be said that the miniature is a protective device that is used in electrical equipment and circuits so that when the current exceeds the permissible limit, the circuit is cut off so that other equipment is not damaged.
## Miniature keys use two mechanisms for their operation.
1. Bitmal function for overload protection
2. Magnetic function for short circuit protection
Miniature switches of Schneider company are divided into 4 parts, single-bridge, double-bridge, three-bridge and four-bridge, in terms of the number of bridges, and in terms of the cut-off time, they are divided into fast-acting and slow-acting states. They are also divided into K, D, C, B and Z types in terms of application.
1. Type B miniature switch: This type of miniature switch is mostly used at home and cuts off the overload current between 3 and 5 times the nominal current in a certain time. These types of switches are considered fast-acting.
2. Type C miniature switch: This type of switch is mostly used in industry and it cuts the overload current between 5 and 10 times the rated current in a certain time. This type of switch is considered a slow-acting type.
3. D-type miniature switch: This type of switch is mostly used in special industries such as transformers and cuts the overload current 10 to 20 times the rated current.
4. K type miniature key: This type of key is used in transformer and engine. It is usually between types C and D.
5. Z-type miniature switch: This miniature will issue a shutdown command at a specific time when the passing current exceeds the rated current. This key is used in very sensitive circuits.
Note: accessories can be installed on the miniature keys to detect the on and off status or alarms.
