Spring steel compression release mechanical springs for small assemblies. This set delivers reliable action in compact mechanisms using durable spring steel. The product offers wire diameter options and two length choices to fit a range of applications, including a 0.9 mm variant packaged as five pieces. Key attributes Material: spring steel Function: compression release, mechanical spring Wire diameter options: 0.8 mm or 0.9 mm Length options: 20 mm (standard); 0.9 mm variant length of 10 mm Quantity in the 0.9 mm variant: 5 pieces Purpose: designed to provide a precise force in small mechanisms and levers Specifications and compatibility Suitable for small, compact mechanisms requiring a quick, reliable after actuation Choose 0.8 mm or 0.9 mm wire diameter based on required stiffness and fit Standard length is 20 mm; the 0.9 mm set includes 10 mm long springs, five pieces Applications and use cases Use case 1: action for a miniature trigger or lever in model kits, RC devices, or other hobby electronics Use case 2: compression in small latch or contact mechanisms within compact enclosures or cabinets Use case 3: replacement springs in diy robotics or precision tools where space is limited and a compact force is needed Notes Ensure dimensions match your design requirements: wire diameter, length, and available quantity Suitable for repeated cycling within the elastic limit of the spring steel to maintain consistent performance Handle with appropriate tools to avoid overcompression and to preserve spring integrity
