WebTime 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-open.

The electrical contact of a pressure switch is typically NC (Normally Closed), NO (Normally Open), or changeover. Changeover means that the common terminal switches between two contacts, allowing the switch to be used in either NC or NO operation. Changeover contacts are also referred to as SPDT (Single Pole Double Throw).
