Normally closed switch means

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. WebElectrical contact. Schematic for an electromechanical relay showing a coil, four pair of normally open and one pair of normally closed contacts. An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. [1] Each contact is a piece of electrically conductive material ...
