Its full name is Double pole single throw. A switch is designed to connect two wires in a line. Such switches have two poles. Both poles are used to open and close the circuit simultaneously. The two poles are connected by a non-conductive material, which has a handle. By turning this handle, two circuits are controlled, one circuit is disconnected and the other circuit is connected. Each Input Terminal connects with 2 output Terminals, and all 4 output Terminals are separate.

A timer is a type of time switching device that controls and controls electrical circuits and electrical and electronics devices through time setting (on/off). Timer is basically 8 pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has two common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time Curve where the Tripping Time Becomes Less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.

Defrost heaters are used to melt ice formations in refrigeration equipment. They are caused by defrosting water, which freezes inside the lower freezing cold room, collecting in trays or defrost lines. For trays, tubular heaters of various designs are installed. To defrost pipes, wire heaters are wrapped around the pipe. Defrost cable heaters are made in two models, with or without self-regulating elements. Defrost heater is used to help icing conformation in the Refrigerator and is controlled by a Thermostat.

Biometrics is a scientific and technological authentication method based on biology and is used in data assurance. Biometrics refers to statistics about humans. Biometrics identification is a widely used identification method in computer science. It is used to monitor an individual. Biometric identifiers identify a person by looking at certain physical characteristics. Biometric devices convert a person’s personal characteristics into digital codes.

CFL stands for Compact Fluorescent Lamp which is an improved version of tube lights of earlier days. Like tube lights, it is a vacuum glass tube with fluorescent powder coating which is not as long and straight as tube lights but curved/twisted compact, or small in size. Like a tube light, it has electrodes or filaments at both ends. But in this case, instead of a choke, there is an electronic circuit that drives the Compact Fluorescent Lamp. Because the red wave is less in the light of the Tubelight and Compact Fluorescent Lamp, the object looks a little pale or the correct color of the object does not appear.
