3-position switch with key, robust metal key - right and center positions ZB4BG04

Key switch – reliability and safety in one

This three-position key switch is a solid solution for applications requiring access control and protection against unauthorized operation. Made of durable materials, it ensures long-lasting and trouble-free operation in various industrial and commercial conditions. Designed for mounting in 22.5 mm diameter holes, it offers a high degree of protection against environmental influences.

Design and application

The switch is characterized by a stable construction that ensures reliable switching between three positions – right, center and left (after removing the key). The metal front ring in chrome color gives it an aesthetic look and increases resistance to mechanical damage. The key allows only authorized persons to change the settings, making it an ideal solution in places where restricting access is important. The IP66 protection rating guarantees resistance to dust and water jets, allowing its use even in harsh industrial conditions.

Key features and benefits

• Three switching positions: allow flexible control of devices or circuits.
• Stable key: ensures security by limiting access to change settings only to those with a key.
• Durable construction: the metal front ring and solid construction guarantee a long service life.
• High degree of protection (IP66): protects against dust and water, ensuring reliable operation in harsh conditions.
• 22.5 mm hole diameter: facilitates mounting in standard control panels.
• Chrome front ring: gives an aesthetic look and increases corrosion resistance.
• Non-self-returning: the switch position is maintained until re-intervention with the key – important where certainty of setting is needed.

This switch finds application in a wide range of devices and machines, such as control panels, electrical cabinets, production machines and anywhere where access control and protection against unauthorized operation or change of settings are required. It is a reliable solution for both professional installers and end-users looking for a safe and durable control element.
