Function: NC (normally closed) momentary push button — trigger opens the circuit when pressed, returns to closed when released. Designed as a micro, short-term on/off (momentary) switch. Package contents: 20 x short-term on/off push buttons (micro momentary push button). Why you need it: provides reliable momentary switching for repairs, prototypes, or production builds where a normally closed trigger-open response is required. Buying 20 pieces ensures spare parts and consistent behavior across multiple units or projects. Key benefits: Consistent momentary action: each press opens the circuit only while held, returning to closed automatically. Bulk pack for cost-effective replacements and multi-unit installations. Micro form factor: small footprint suitable for compact electronic assemblies and tight spaces. Versatile: can be used wherever a normally closed momentary switch is required. Compatibility and performance notes: Intended for use in electronic circuits and devices that accept micro momentary NC switches. Best suited for low-profile PCB or panel mounting where a short-term on/off (momentary) function is needed. Practical advantages: Reduces downtime by keeping spare switches on hand for maintenance or rapid replacement. Ensures uniform switching behavior across multiple control points in a device or system. Typical applications: 1. Prototyping and hobby electronics (e.g., breadboard or PCB testing where a momentary NC input is needed). 2. Control panels and instrument resets that require a trigger-open response only while pressed. 3. Repair and refurbishment of small devices that use micro momentary NC push buttons. Package includes exactly: 20 x short-term on/off push buttons (micro, short-term push button).
