Key switches, also called key-lock switches, are electromechanical devices designed to break/complete the connection using a mechanical key. These switches provide an added layer of security and control in applications requiring a high level of authorisation and access management. A key switch can also control electricity flow and comes with ON and OFF states that require specific keys for unlocking or locking purposes. Key lock switches are the best alternatives, ensuring robust security compared to other switches that do not need a particular key. Key-operated switches are made of durable materials and compact, providing easy integration and an extended lifespan.
Operating Principle of Key Switches
Key switches operate in a simple switch mechanism that needs an appropriate key matching the lock cylinder. With ON or OFF positions, the cylinder accepts the right key and triggers the operation based on specific needs.
Difference Between Key Switches and Comon Switches
A key switch differs from standard switches like pushbutton switches or rocker switches in their activation mechanism, security levels, and environments. Key switches intentionally activate or deactivate the machinery or system, while standard mechanical switches can be unintentionally activated using buttons.
Furthermore, key switches provide high levels of security by preventing unauthorised access and control compared to common switches lacking similar protection. Additionally, common switches are primarily found in household appliances where specific features of key switches are not required.
Most Popular Types of Key Switches
Key switches come in various types based on environments and applications. Some of the best key switch types include:
