Buy key switches

By using key switches and key pushbuttons, you add additional safety to various switching operations. These electrical switches are equipped with a lock and can only be operated by inserting the associated key into the cylinder. A distinction is made between momentary and latching switches.

Latching switches trigger a pulse when the key is turned and then return to their initial position, while switches can remain in various positions. These mechanisms prevent misuse, increase theft protection and prevent accidents caused by unauthorized operation.

Typical applications include car ignition locks, garage doors and complex machinery. Key switches are also used to activate and deactivate alarm systems.
