How Does the Elock EL-KS3L Key Switch Work?

First, an authorized user inserts the key into the switch.

Next, turning the key changes the electrical contact between the common terminal and the selected contact.

The connected access control system then responds according to its wiring and configuration.

For example, the switch can provide a key-operated release signal to a compatible door controller.

In addition, the LED can display a configured electrical status when connected to an appropriate supply.

Therefore, the Elock EL-KS3L Key Switch offers a simple manual control option for compatible security installations.

However, the switch does not authenticate users electronically. It also does not operate as a complete standalone door controller.

Common Applications

The EL-KS3L suits installations where authorized personnel need a physical key-operated control.

• Corporate Offices: Provide key-operated access functions at selected entrances.
• Commercial Buildings: Support manual control of compatible electronic doors.
• Warehouses: Add authorized key control to designated access points.
• Factories: Support controlled operation at restricted entrances.
• Security Control Rooms: Provide a physical switch for approved security functions.
• Building Access Systems: Work with compatible door release and control circuits.

Before installation, contractors should confirm the required switching behavior, contact load, and mounting arrangement.

LED Key Switch vs. Push-to-Exit Button

An LED key switch requires a physical key to operate its contacts. In contrast, a standard push-to-exit button can be operated without a key.

For example, a facility may use the EL-KS3L for authorized maintenance or security control. Meanwhile, a push-to-exit button may serve normal exit requests where appropriate.

However, a key switch should not replace required emergency exit hardware or compromise safe egress.

Door Access Control Compatibility

The EL-KS3L supports compatible door access controllers and switching circuits.

For example, installers may connect its dry-contact terminals to a controller input. The controller can then perform a configured action.

The switch also has dedicated LED connections. However, installers must check the correct LED supply and wiring requirements before connecting power.
