What is a relay delay in the electric circuit?

A relay is a kind of electrical switch which interconnects an electric circuit. It works using an electromagnet which makes or breaks a contact when a voltage is applied to the coil. It is activated immediately when voltage is applied. In a relay delay, the electromagnet is not energized instantaneously when a voltage is applied. It is activated after a fixed set of time or programmed time.Various types of delay mechanism are available, some fixed, some with variable time delay. The timing mechanism can be mechanical, motorized or electronic.

How can I test a limit switch to ensure it is functioning properly?

To test a limit switch, you can use a multimeter to check for continuity when the switch is activated. Disconnect the switch from the circuit, set the multimeter to the continuity setting, and touch the probes to the switch terminals. When the switch is activated, the multimeter should beep or show continuity. If there is no continuity, the switch may be faulty and needs to be replaced.
