Frequently Asked Questions

What is a maintained key switch?

A maintained key switch remains in its selected position until the key is turned again, unlike a momentary switch that automatically returns to its original position.

Can the KS-001 be surface mounted?

Yes. The KS-001 can be surface mounted when used with the optional surface surround.

Is the key removable in both positions?

Yes. The key can be removed in either switch position.

What is the difference between the single pole and double pole versions?

The single pole version provides one set of COM, NO, and NC contacts, while the double pole version provides two independent sets of contacts. This allows the double pole model to switch or control two separate circuits from the same keyed operation.

What does keyed alike mean?

Keyed alike means multiple switches can be operated using the same key, simplifying management across larger installations.

What contact outputs are available?

The KS-001 features COM, NO, and NC contacts for flexible integration with a wide range of systems.

What is the KS-001-3POS used for?

The KS-001-3POS is a 3-position double pole key switch designed for applications where keyed control of multiple switch positions is required, such as open / off / close or similar control functions, depending on the connected equipment.

What is the difference between a maintained and momentary key switch?

A maintained key switch stays in the selected position until the key is turned again. A momentary key switch only changes state while the key is being turned and then returns automatically to its normal position.

What does NL mean on the KS-001-NL models?

NL indicates a blank faceplate version with no engraved legend. The KS-001-NL is the blank single pole version, while the KS-001-NL-DP is the blank double pole version.

Can the KS-001 be used with access control systems?

Yes. The KS-001 is designed for integration with access control systems, electric locks, magnetic locks, gate automation systems, roller shutters, barriers, and other compatible low-voltage control equipment.
