Key switch EB1621533255 flat design OFF-ON, panel-mounted key-operated switch

Key switch EB1621533255 is a flat-design, panel-mounted key-operated ON/OFF switch designed to provide controlled manual switching in environments where access must be limited. The switch is intended for installation in control panels, security systems, machinery and equipment, enabling authorized personnel to change circuit state between OFF and ON. Its low-profile form factor allows integration into compact panels while the keyed actuator reduces the risk of accidental or unauthorized operation.

Advantages

The flat design minimizes protrusion from the panel surface, promoting a neat installation and reducing the chance of accidental contact. The keyed mechanism ensures that only holders of the matching key can operate the switch, increasing operational security. Panel-mounted configuration provides a stable and accessible mounting method for control enclosures. The simple two-position OFF-ON functionality facilitates straightforward control and integration with existing electrical circuits.

Suitable for

• Control panels in industrial and commercial equipment
• Access-restricted security systems
• Machinery start/stop controls where authorized operation is required
• Equipment cabinets and operator consoles

Key specifications

• Operation: Key-operated two-position switch (OFF / ON)
• Form factor: Flat / low-profile design for panel mounting
• Mounting type: Panel-mounted installation
• Actuation: Mechanical keyed actuator to restrict access
• Use environment: Suitable for control panels, security and machinery applications

How to use

Install the switch into the appropriate cut-out in the control panel and secure it according to panel thickness and enclosure specifications. Connect the switch terminals into the circuit following the wiring diagram of the system: the switch provides a simple open/closed function corresponding to OFF and ON positions. Use the supplied or matching key to operate the actuator; rotate the key to change the position and remove the key if required to lock the switch in the selected state. Follow standard electrical safety procedures and ensure power is isolated during installation.

Usage recommendations

Use the key switch in locations where limited access is required and combine it with clear labeling so authorized operators can identify its function. Regularly inspect the mechanical key mechanism for wear and clean contacts during maintenance intervals. Avoid exposing the switch to excessive moisture or contaminants unless the installation environment and switch sealing are specified for such conditions.
