Rotary switch with key – a reliable choice for various applications

This two-position rotary switch with key, designated SP22-SAA-20, is a solid and functional solution for controlling electrical circuits. Manufactured by Spamel, it combines durability, safety and ease of use. Designed for mounting in 22 mm diameter holes, it will work well in both industrial applications and building installations.

Construction and operating parameters

The switch is characterized by a non-self-returning design, which means that once set to one of the two positions, it remains stable. The locking mechanism is implemented using a key, which provides additional security and prevents accidental change of settings. The plastic housing and gray front ring provide an aesthetic appearance and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jets – ideal for environments requiring increased resistance to external factors. Made with a screw connection, it allows for easy and secure cable mounting.

Application and benefits

This switch finds application wherever reliable control of devices or electrical circuits with position locking is required. It is perfect for:

• Machines and industrial equipment: as a control element for the operation of motors, pumps or other devices.
• Control panels: enabling safe switching on and off of individual circuits.
• Building installations: e.g. for controlling lighting in technical rooms or warehouses.
• Applications requiring protection against accidental change of settings: the key lock prevents unauthorized access to control functions.

Thanks to two normally closed contacts (2NC) and no normally open (0NO) or changeover (0) contacts, this switch allows for effective switching of electrical circuits. The supply voltage range from 24V to 230V provides a wide range of applications in various electrical installations.
