2-position rotary switch key 1 NC 2 NO nickel-plated ring ST22-SAA-12. ST22-SAA-12\.

Universal rotary switch – reliability and durability in every circuit

This 2-position rotary switch with a key is a solid solution for controlling devices requiring a reliable and safe disconnection. The construction with a nickel-plated ring ensures resistance to corrosion and mechanical damage, which translates to a long service life even in harsh industrial conditions.

Construction and application

The switch is designed for mounting in 22 mm diameter holes. Made of high-quality materials, it guarantees stable operation and reliable performance for a long time. Screw connection ensures secure and durable electrical connections, minimizing the risk of errors in the circuit. A wide range of supply voltage (24…230 V) makes it a universal element that can be used in many installations. The IP65 protection class means resistance to dust and water jets, allowing it to be used both indoors and outdoors.

Advantages and characteristic features

• Durable construction: The front ring made of plastic and the nickel-plated finish provide resistance to mechanical damage and corrosion.
• Safety of use: Non-latching (non-self-returning) prevents the switch position from being accidentally changed, eliminating the risk of accidental circuit disconnection.
• Versatility: A wide supply voltage range (24…230 V) allows use in various electrical installations.
• Protection against external conditions: IP65 protection class provides resistance to dust and water, allowing operation in harsh environmental conditions.
• Contact configuration: It has 1 normally closed contact and 2 normally open contacts, providing flexibility in connecting various loads.
• Easy installation: Screw connection facilitates quick and secure connection of wires.
• Key element: The use of a key increases security, preventing unauthorized persons from accidentally changing the switch.

This switch is an ideal choice for installers looking for a reliable component for building safe and durable electrical installations, as well as for end users who value functionality and solid workmanship.
