2-position rotary switch key 2 NC 4 NO nickel-plated ring SP22-SAA-24. SP22-SAA-24\.

Universal 2-position switch – reliability and functionality in one

This rotary switch with key, designated SP22-SAA-24, is a versatile solution for controlling electrical circuits. Designed for both professional installers and end-users, it provides safe and convenient operation. Manufactured by the renowned Spamel, it guarantees solidity and long-lasting performance.

Construction and application

The switch is designed for mounting in 22 mm diameter holes. Its construction based on screw connections ensures secure and durable wire connections. The switch has two positions, allowing control of two independent circuits or one circuit in two operating modes. The key prevents accidental switching, increasing safety, especially in applications requiring protection against unauthorized access. The front ring made of plastic in gray color adds aesthetics and protects against mechanical damage.

Parameters and characteristic features

The device is characterized by a wide supply voltage range from 24 to 230 V, making it compatible with various electrical systems. The IP65 protection class provides resistance to dust and water pressure, allowing installation in harsh environmental conditions. It has 4 normally open (NO) contacts and 2 normally closed (NC) contacts, providing great flexibility in configuring control circuits. Non-latching means the switch remains in the set position until manually switched. The mounting hole diameter is 22 mm and the hole width is also 22 mm.

Good to know: The C characteristic of the contacts allows them to react more slowly to short current surges, therefore they can withstand starting devices with a motor or other elements generating high starting currents. Short-circuit protection of the switch tracks is 10 A (fast-blow fuse).
