What is mechanical life of the electrical switches

The mechanical life of electrical switches refers to the number of cycles or operations a switch can reliably perform before it may start to degrade or fail. It is a measure of the switch's durability and longevity. The mechanical life of a switch can vary depending on factors such as the quality of the switch, the type of switch, the application, and the operating conditions.

Different types of switches have different mechanical life ratings. Here are some general estimates for mechanical life:

Push-button switches: Mechanical life can range from 10,000 to 1 million cycles, depending on the quality and type of switch.

Toggle switches: Mechanical life can range from 10,000 to 100,000 cycles or more.

Slide switches: Mechanical life can range from 5,000 to 50,000 cycles or more.

Rotary switches: Mechanical life can range from 10,000 to 100,000 cycles or more.

It's important to note that these estimates are approximate and can vary significantly depending on the specific switch and its manufacturer. Higher-quality switches, often used in industrial applications, can have higher mechanical life ratings compared to consumer-grade switches.

Additionally, it's worth considering that some switches have electrical ratings alongside their mechanical life ratings. Electrical ratings specify the maximum voltage and current that a switch can handle reliably.

When choosing switches for a particular application, it's essential to consider the expected usage and select switches that meet the required mechanical and electrical requirements to ensure reliable operation over the desired lifespan.
