The timer box acts like a time-delay relay. Many delay boxes actually have an internal relay to switch output current, but some models have solid state transistorized output circuits. The transistorized type made today almost always use power MOSFET type output circuitry. Drag racing delay boxes are designed to operate from the vehicles 12 volt ...
Time-delay relay contacts must be specified not only as either normally open or normally closed, but whether the delay operates in the direction of closing or in the direction of opening. The following is a description of the four basic types of time-delay relay contacts. First, we have the normally open, timed-closed (NOTC) contact.
The company was founded as “Schleicher Relais Werke” by Otto Schleicher in 1937. In 1958, “Schleicher Relais Werke” presented the MZ 54 time-delay relay at the first industrial trade fair in Hannover. It was the first multifunctional time-delay relay, and due to its purely electromechanical basis, is still used in many ways.
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.
A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.
