SKU PK396193
The Schneider 3-position key switch is designed for secure electrical access control in industrial automation, gate systems, and machine safety circuits. Its primary function is to restrict operation of equipment by ensuring only authorised users with the key can activate or disable a machine.
This unit features a robust round construction with chrome plating for enhanced durability and resistance to wear. The key mechanism is smooth and reliable, making it ideal for repeated daily operation on high-traffic sites or production floors. With a wide -40°C to 70°C operating range, it performs reliably in diverse environmental conditions.
- Screw clamp terminal connection - Enables fast and secure installation into control systems.
- Compact circular format - Fits standard panel cutouts for control cabinets or gates.
- Ingenious locking system - Ensures the key switch stays fixed during operation.
- Flexible application - Ideal for controlling automation sequences and electrical interlocks.
This key switch is a vital addition to site access control and machine interface design. Whether deployed in a security kiosk, an automated gate panel or inside an operator enclosure, the unit ensures equipment can only be used by trained personnel. The 3-position mechanism supports custom control schemes and switching logic, from manual override to mode switching.
Its metal design resists corrosion and deformation, while the printed circuit-compatible pins allow for integration in complex control networks. Frequently used in conjunction with control stations, isolators, and safety lockouts, this key switch enhances operational safety and reduces equipment misuse.
HERMEQ stock a wide-range of Entrace Barriers, Traffic Management, Permanent Fencing & Temporary Fencing conforming to all required safety specifications and regulations.
