# How are DIP switches calculated?

## How are DIP switches calculated?

The dip switches are set according to binary calculation meaning that every dip switch can feedback only the values 0 and 1. First dip switch is 0 (computers start counting from 0, not from 1), so when it’s switched on it says 20 = 1. Dip switch 2 has the value 1 if switched on, so it is 21 =2.

### What is the purpose of DIP switch?

In a nutshell, the role of DIP switches is to allow users to control the flow of electricity around a printed circuit board (PCB), expansion card or other electronics/computer peripheral, and therefore change the operating mode of a device.

What controls a variable speed furnace?

Variable speed furnaces contain an ECM (electronically commutated motor) blower motor, which allows the furnace to operate at higher efficiency levels. They are DC motors that use a built-in inverter and magnet rotor, delivering better energy efficiency than furnaces with AC motors.

What is the difference between a DPST and a DT switch?

The DPST switch, for example, has four terminals, but it is a DP, not a 4P switch. Throw refers to the extreme position of the actuator: ST switches close a circuit at only one position. The other position of the handle is Off. DT switches close a circuit in the Up position, as well as the Down position (On-On).

## What is the difference between a DP and SP switch?

Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked). Do not confuse ‘pole’ with ‘terminal’. The DPST switch, for example, has four terminals, but it is a DP, not a 4P switch.

### What are the different types of DT switches?

A DT switch can also have a center position (frequently On-Off-On). Single pole/throw and double pole/throw switches are by far the most common switches, but triple and quadruple configurations are also available. They are commonly denoted 3PST, 3PDT, 4PDT, etc.

What is the difference between a DPDP and St switch?

DP switches control two independent circuits (and act like two identical switches that are mechanically linked). Do not confuse ‘pole’ with ‘terminal’.
