2-position rotary switch key 1 NO 1 NC nickel-plated ring ST22-SAA-11. ST22-SAA-11\.

Rotary switch – reliability and durability in every circuit

This 2-position rotary switch with a key is a solid solution for controlling electrical circuits. Made of high-quality materials, it ensures long-lasting and trouble-free operation even in harsh conditions. The nickel-plated ring adds to its aesthetic appearance and corrosion resistance.

Construction and mounting

The switch has screw connections, which facilitate quick and secure mounting in the installation. A hole diameter of 22 mm and a hole width of 22 mm ensure compatibility with standard distribution panels. The IP65 protection rating guarantees resistance to dust and water jets, making it an ideal choice for indoor and outdoor applications.

Application and functionality

The device is designed to control lighting, heating devices or other electrical loads. Thanks to the two switching positions (closed and open) and a single normally open and normally closed contact, it offers simple but effective control over the circuit. The key actuator provides additional security, preventing unauthorized persons from accidentally turning the device on or off. The supply voltage range of 24…230 V allows for universal use in various electrical installations.

Characteristic features:

• Durable construction: Made of high-quality plastic and metal, resistant to mechanical damage and external factors.
• Tightness: IP65 protection rating protects against moisture and dust, increasing its reliability in demanding working conditions.
• Safety: The use of a key prevents accidental manipulation of the switch settings.
• Versatility: Wide supply voltage range (24…230 V) allows use in various electrical installations.
• Aesthetics: Gray front ring and nickel-plated finish give it an elegant look.
• Non-self-returning: After being set to the closed or open position, it remains in that position until the position is changed again – this ensures stable circuit operation.
