When it may not be suitable
This actuator is not intended for use in environments where rapid, non-secure switching is required, as the need for a key may impede quick response times. It is also not suitable for outdoor installations without additional protective enclosures to prevent environmental damage.
Key specifications
Mounting diameter: 22mm
Color: Black
Operation type: Key-operated
Application: Industrial control systems
How to use
To install the actuator, insert the device into a pre-drilled 22mm hole on the control panel and secure it using the provided locking nut. Ensure the gasket is properly seated to maintain the integrity of the panel. Once installed, the switch is operated by inserting the key and turning it to the desired position. Always remove the key after operation if you wish to lock the switch in a specific state or prevent further unauthorized use.
What to consider before purchase
Verify that your control panel has a standard 22mm mounting aperture.
Ensure the switch configuration matches your electrical circuit requirements.
Confirm that the key access level aligns with your facility's security protocols.
Usage recommendations
Regularly inspect the key mechanism for debris and ensure the mounting nut remains tight to prevent vibration-induced loosening. Keep spare keys in a secure, accessible location for authorized personnel only.
