What are the 5 types of switches?
Types of Switches
- SPST (Single Pole Single throw)
- SPDT (single pole double throw)
- DPST (double pole, single throw)
- DPDT (double pole double throw)
What is the standard height of switches?
48 inches
For a majority of rooms, builders tend to place the bottoms of light switches 48 inches above the floor. This is a comfortable height for most home dwellers when sitting or standing, plus it makes it easier to install switches during construction.

The height from the floor to the middle of the switch plate should not exceed 48 inches, and the minimum height should not be less than 15 inches. When the switch is over a counter that has a knee space, and the counter depth exceeds 20 inches, the maximum height of a switch is reduced to 44 inches.
Is standards for electrical wiring?

What is the difference between IEC and ISO?
The scope of ISO covers standardization in all fields except electrical and electronic engineering standards, which are the responsibility of the International Electrotechnical Commission (IEC). The work in the field of information technology is carried out by a joint ISO/IEC technical committee (JTC 1).
What is the difference between IEC and UL?
IEC standards specify the minimum device safety requirements. UL standards, in contrast, specify comprehensive technical details in terms of product safety and application. In addition to standards development, the UL is also responsible for certification (general third-party certification) as well as field acceptance.
