Key retention means the key can only be removed when the switch is in a specific position, such as 'Off'. This is a critical safety feature to prevent unauthorized operation.

What are Keylock Switches components?
Keylock switches are electromechanical devices used to restrict access to equipment or modes of operation. Selection hinges on contact configuration (SPST/DPDT), key retention logic, IP rating for environmental sealing, and the physical mounting diameter (typically 16mm or 22mm).
How to Choose Keylock Switches Components
Focus on the mechanical and electrical constraints of your enclosure and control logic.
Mounting Diameter
Standardize on 16mm, 22mm, or 30mm cutouts to ensure compatibility with existing panel designs.
Key Retention
Determine if the key must be removable in all positions or only in specific states for safety interlocks.
Contact Rating
Verify the switch can handle your circuit's voltage and current, especially for inductive loads.
IP Rating
Select IP65 or higher for outdoor or washdown environments to prevent ingress of dust and moisture.
Switching Logic
Define the required throw (2-position vs 3-position) and momentary vs. maintained action.
