2Channel Bluetooth Controlled Relay w/ Form “C” Contact for iPhone JB
Form C Contact. Form x = no with both terminals disconnected when off. Form c contact assembly has three terminals.
These contacts have a common terminal. A form c contact is also called spdt. This type of contact controls two circuits: 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). One normally open and one normally closed. Form c contact assembly has 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. A form c isolated relay would have three terminals. They can be part of any type of a relay or auxiliary switch.
It is hermetically sealed with 3 leads: It is hermetically sealed with 3 leads: When operated the common contact will swing from the normally closed contact to the normally open contact. Form y = nc 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. A form c contact is also called spdt. A form c isolated relay would have three terminals. One normally open and one normally closed. Web a dry contact is one that is a hard contact such as a relay or switch (as opposed to a triac or transistor). 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. Form c is a combination.
