What is the principle of timing switch?

The delay switch is an electronic component, which can delay the operation of the switch circuit. It usually consists of a trigger and a time link. When the trigger receives the input signal, it will start the time link. During the time link operation, the output signal is uncertain. When the time period ends, the output signal will switch to a new state.

Commonly used delay switches include digital time delay relay, transistor delay switch, circuit board time delay relay, electronic time delay relay, etc.

Then it is explained that the delay switch is widely used in automatic control system, temperature control system, security system, home appliance control, automotive electronics, medical equipment and other fields.

For example, in an automatic control system, a delay switch can be used to delay the system restart or shutdown, so as to avoid the system shutdown caused by sudden failure. In temperature control system, delay switch can be used to delay the action of temperature regulator to reduce unnecessary energy waste. In the control of household appliances, the delay switch can be used to delay the turn-off of appliances to avoid the discomfort caused by sudden turn-off.

The delay switch can be realized by circuit or digital time delay relay, and the output can be controlled by preset time. The delay element can be realized by digital time delay relay, transistor delay switch, circuit board time delay relay, electronic time delay relay, etc.
