A limit switch is a device that is under the furnace provided plenum. A limit switch also works as a safety device for the oven. If the temperature inside the plem becomes too hot, disconnect the gas supply to the burners to avoid overheating the oven and heat exchanger.

When a button is opened until it is activated, it is said to be opened normally (NICE short). On the contrary, if a button acts normally as a short circuit, if it is not activated, it is called a closed switch normally (NC). NC stops first by activating the switch creates an open circuit.

An electrical switch is a device that interrupts the flow of electrons in a circuit. The switches are mainly binary devices, fully switched on or off, and the light switches have a simple design. When the switch is switched off, the circuit breaks down and the supply flow is interrupted. The circuits consist of a source of power and charge.

Rotating limit switches detect and are activated by rotary motion. Switches are devices used to break electrical circuits. Usually they involve a rotary axis that joins the equipment to be limited or controlled. When the axis reaches a fixed number of towers or a fixed angle, the switch is activated.

Separates the part of the circuit where the power error occurs. The insulators are applicable to high voltage devices as transformers. The main function of the insulator is to block the continuous current signals to allow the circulation of alternating current signals. The switch is a type of protective device that works as a switch.
