Camlock Systems offers a diverse range of robust switchlocks designed to provide an extra layer of security and control.

Our switchlocks, also known as key-operated switches, ensure restricted access to vital functions, making them perfect for charging units, machinery, and alarm panels.

Here's what sets our switchlocks apart:

Toggle & Momentary Switches: Select from toggle switches for simple open/close operations or momentary switches that require a turn-and-hold action.

Reprogrammable Keys: Easily restore security with our changeable key combination feature in case of lost or stolen keys.

Advanced Security Mechanisms: Developed with customer needs in mind, our cylinders are designed to protect a wealth of commercial and OEM applications, offering mid to high-security options to choose from. Our flagship Radial Pin mechanism balances physical security and flexibility, providing high manipulation and attack resistance in a variety of high-quality materials. We also offer traditional flat key options and more complex high-security mechanisms with patent protection and key registration.

Waterproof Options: Our range includes waterproof switchlocks, ensuring reliable performance in challenging environments.

Security Levels: Choose from various security levels to match your specific needs, from basic to high-security options.

Cost Levels: We offer switchlocks at different price points, ensuring you get the best value for your budget without compromising on quality.

Our switchlocks have proven their reliability and effectiveness in numerous applications, including:

Roadside Cabinetry: Providing robust security for outdoor equipment.

Backup for Electronic Lock Systems: Offering a dependable secondary layer of security.

All our switchlocks comply with LVD and CE regulations.

Pushlocks

Pushlocks (or ‘plunger locks’) are spring-loaded cylindrical locks with a locking pin at the rear.

Generally, these are used on sliding doors or other applications where the lock is required to prevent lateral movement.

Normally, pushlocks work on a push-to-lock/key-to-unlock principle. Pushing the lock ‘head’ moves the central barrel and the locking pin, which protrudes at the rear to lock the application. A turn of the key allows the spring-loaded barrel to ‘pop out’ to the open position and retract the locking pin. As an alternative, we also offer a key-to-lock/key-to-unlock action.

These versatile locks are used for securing display cases, cabinets, street furniture, cupboard doors, boxes, drawers, juke boxes, pool tables and many other applications.

Many of the radial pin tumbler pushlocks feature our award winning ‘Octagon’ mechanism, which makes unauthorised key duplication virtually impossible. We offer conventional 7-pin and 10-pin types for when unit cost is the primary requirement.

You also have the option of a changeable combination (or ‘reprogrammable’) type known as ‘Camatic’, which enables you to restore security quickly and easily if a key is lost or stolen.

In addition, the range includes disc tumbler pushlocks and a simple, tamper-proof, triangular drive ‘spanner lock’.

Two-wire and three-wire locks

Why do we have two versions of wiring and what are the fundamental differences between the two?

Two-wire and three-wire electronic locks are two different types of locks used for various security applications. The primary difference between them lies in their wiring and functionality.

Both versions have unique characteristics that define why they are used.

Two-wire:

The two-wire version was the first configuration to be developed in the Series 100 lock. The primary reason for this was that it could be used as a direct replacement for solenoid operated locks.
Additionally, a two-wire version is ideally suited for use when the lock is being powered by batteries, this is because the lock will only use power when being operated, conserving energy by avoiding the locks being powered continuously.

Two-wire electronic locks, are simpler in terms of wiring and functionality.
Two-wire electronic locks typically require only two wires to operate: one for power and one for ground (or common).

The two-wire version can be connected in two different ways.

Power can be applied constantly to the positive wire (red) and then a circuit can be made by controlling the negative wire (black). Alternatively, connection can be made with the negative wire (black) and then the circuit can be completed by applying the positive wire (red).

The main use of two-wire operated locks is when they are being powered by batteries or need to be legacy compatible.

Our locks that are available in two-wire configuration: - S100, S500 and S600.

Three wire:

The three-wire version has two different versions (positive trigger and negative trigger).
The main difference between the three-wire over the two-wire is that the three-wire has power connected to the lock constantly. By connecting the lock this way we enable more options to control the lock.

Three-wire electronic locks are more versatile than two-wire locks.
They require three wires for operation: one for power, one for ground, and one for control.

With three-wire we can choose to hold the lock in an open (unlocked) position for prolonged periods or keep the lock in an unlocked state, for example: - if the door is in the open position, this is a feature that is particularly attractive to the parcel locker sector as it allows packages to be added and removed without the lock closing. This function is achieved by maintaining the connection to the trigger wire (Blue).

In summary, the key difference between two-wire and three-wire electronic locks is their level of complexity and functionality. Two-wire locks are simpler and typically used in basic security applications, while three-wire locks offer more advanced features. The choice between them depends on the specific configuration of existing equipment and the complexity of the overall security system.
