Normally closed vs normally open relay
WebREVIEW: Time delay relays are built in these four basic modes of contact operation: 1: Normally-open, timed-closed. Abbreviated “NOTC”, these relays open immediately upon coil de-energization and close only if the coil is continuously energized for the time duration period. Also called normally-open, on-delay relays. 2: Normally-open, timed ... WebNormally opened or closed refers to the state of a contact attached to an opening. When talking about circuits or zones on an alarm panel, "normal" indicates the normal state of the opening being protected. For doors and …

WebHow relays work and how to connect the contacts to a lamp using both Normally Open NO and Normally closed NC contacts. WebWhen a magnetic field is brought close enough to the outer casing of the reed switch, the contacts inside are pushed together or apart. This makes or breaks the circuit, depending on the direction of movement. In a normally open reed switch - the most common type - the two contact blades are positioned slightly apart, with an air gap between them.
