Keylock switches to protect against unauthorised activation

A keylock switch is a switch that can only be activated with the corresponding keylock. They are used, for example, as additional security for heavy machinery, or to open and close gates and doors. They are also useful to protect against vandalism for publicly accessible switching systems, such as elevators. You can find a wide variety of different keylock switches in our range that will suit your project.

For example, we stock keylock switches with the following features:

  • keylock switches with different thread sizes
  • keylock switches in various designs
  • keylock switches with up to five positions

Keylock switches from our premium partner NKK Switches

A keylock switch is an electric switch that includes a lock for safety purposes. This way the switching process can only be performed by authorised persons with the corresponding keylock. When the keylock is turned in the switch a certain impulse is triggered. Used in elevators, for example, certain floors can be selected. They can, however, also be used to switch on an electric circuit or operate potentially hazardous machines safely. There are also many other applications for this kind of switch. At ALDERS we bring to market keylock switches by NKK Switches, because these convince with their outstanding quality and high reliability. At ALDERS you can chose between the SK and the CK series by NKK Switches. The keylock switches of both series are very robust and have a very low contact resistance in the milli-ohm range. They also last for a long service life of 30,000 switching operations. Another advantage of the CK series is the self-cleaning sliding contact that additionally ensures high reliability and a long service life.
