WebIn a normally open reed switch - the most common type - the two contact blades are positioned slightly apart, with an air gap between them. This leaves the circuit they are attached to incomplete until a magnetic force is introduced. In a normally closed switch, the contacts are already touching when at rest. 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. can shingles affect your bowels
