Maintained vs. Momentary Switch Locks
The switch function determines what happens electrically when the key is turned. Selecting the correct function depends on whether the equipment needs to remain in its selected state or only receive a temporary input.
Locking Systems can help match the switching function, key system and electrical configuration to the equipment being controlled.
Choosing the Correct Switch Lock
- Maintained or momentary operation
- Required electrical contact configuration
- Voltage and current requirements
- Terminal or lead configuration
- Required security level
- Keyed alike or keyed different
- Existing key-code compatibility
- OEM installation requirements
Where Are Key-Operated Switch Locks Used?
Switch locks are used when equipment or a system function should only be activated by someone with an authorized key.
Control Panels
Restrict control functions on commercial and industrial panels.
Industrial Machinery
Authorize machine activation and operator-controlled functions.
Elevators
Control authorized functions and service operations.
Gaming Equipment
Protect operator and service-controlled functions.
Vending Equipment
Restrict key-operated service or equipment functions.
Kiosks
Control maintenance, reset or service functions.
Electrical Equipment
Restrict switching functions within controlled systems.
OEM Equipment
Integrate key-controlled operation into manufactured products.
Switch Lock Function Options
Match the electrical switching behavior to the function the authorized key holder needs to control.
Maintained Operation
The switch remains in the selected electrical state after the key is turned until the key is returned or the switch is moved to another position.
Momentary Operation
The switch provides a temporary electrical input while activated and returns to its normal state when released.
Custom Configurations
OEM applications may require different contact arrangements, terminal styles, keying structures or switch functions based on the equipment design.
Integrate Key-Controlled Switching Into Your Equipment
For equipment manufacturers, the switch lock becomes part of the machine’s operating interface. Locking Systems can help identify switching behavior, electrical connections, mounting requirements and keying that fit the product design.
Switch locks can support machine activation, service modes, reset functions, operator authorization and other controlled actions across a wide range of equipment.
OEM Configuration Considerations
- Switch function and contact behavior
- Terminal style and electrical connection
- Panel and material thickness
- Key removal position
- Security and key-control requirements
- Existing lock-code compatibility
- Production volume and assembly requirements
Organize Switch Locks by Location, Route or User
Color-coded lock ID rings and tubular key covers can help users quickly identify which keys and switch locks belong to specific equipment, locations or authorized personnel.
More Than a Key Switch Supplier
Selecting a switch lock means matching electrical functionality, mounting, security and key control in one component. Locking Systems helps customers evaluate the complete requirement rather than choosing a switch based only on physical size.

Frequently Asked Questions About Switch Locks
What is a switch lock?
A switch lock is a key-operated lock that also controls an electrical circuit or equipment function. Turning the authorized key changes the electrical state of the switch.
What is the difference between maintained and momentary switch locks?
A maintained switch stays in the selected state after activation, while a momentary switch provides a temporary electrical input and returns to its normal state when released.
Can switch locks be keyed alike?
Yes. Many switch lock systems can be assembled keyed alike or to existing compatible lock codes, allowing multiple pieces of equipment to operate from a common key where appropriate.
Where are key-operated switch locks used?
Common applications include control panels, industrial machinery, elevators, gaming equipment, kiosks, vending equipment, electrical systems and manufactured equipment.
Are high-security switch locks available?
Yes. Switch-lock systems can be configured with stronger key-control technologies for applications requiring greater resistance to unauthorized key use or manipulation.
Where can I purchase switch locks?
Cobra and Cobra 7 tubular switch locks can be purchased directly through LSI Depot. Locking Systems can assist with product selection and specialized OEM configurations.
