Amseco ODC59B Overhead Door Contact FormC TremTech Electrical Systems
Form C Contact. One normally open and one normally closed. Form y = nc with both terminals disconnected when off.
They can be part of any type of a relay or auxiliary switch. Form c is a combination. A form c contact is also called spdt. A form c isolated relay would have three terminals. Form y = nc with both terminals disconnected when off. Form x = no with both terminals disconnected when off. There is a common electrical connection between a contact of each pair that results in only three connection terminals. When operated the common contact will swing from the normally closed contact to the normally open contact. 2 form c (2 co) signal relay contact switching voltage (max)(vac): Web form c is one normally open contact and one normally closed contact with a common terminal between them.
When operated the common contact will swing from the normally closed contact to the normally open contact. These contacts have a common terminal. This is caused by the magnetic field produced by a coil or the magnetic field from a magnet. Web a dry contact is one that is a hard contact such as a relay or switch (as opposed to a triac or transistor). Web form c is one normally open contact and one normally closed contact with a common terminal between them. Form c is a combination. Form x = no with both terminals disconnected when off. A form c isolated relay would have three terminals. This is also called a “changeover” device because the common contact changes from the normally closed position to the normally open position when the coil is energized in a relay or a magnetic field is nearby in a reed switch. It is hermetically sealed with 3 leads: There is a common electrical connection between a contact of each pair that results in only three connection terminals.
