Onoffsäätimet

On/off switches, commonly referred to as onoffsäätimet in Finnish, are simple yet essential devices used to control the flow of electricity in a circuit. They are typically small, rectangular devices with two terminals and a movable lever or button. When the switch is in the "on" position, the circuit is complete, allowing electricity to flow. In the "off" position, the circuit is broken, stopping the flow of electricity.

On/off switches are used in a wide range of applications, from everyday household devices like lights and appliances to industrial machinery and electronic systems. They are often used in conjunction with other components, such as fuses and circuit breakers, to provide additional safety and control.

There are several types of on/off switches, including toggle switches, push-button switches, and rocker switches. Each type has its own unique design and functionality, but all serve the same basic purpose of controlling the flow of electricity.

On/off switches are relatively simple devices, but they play a crucial role in the functioning of many electrical systems. Their design and operation are based on fundamental principles of electricity and circuit theory, making them a fundamental component of electrical engineering.
