This 7mm threaded 2-pin metal momentary push button switch is a compact and durable SPST N/O switch designed for low-voltage electronic projects. Featuring a red round cap with a smooth momentary action, it activates when pressed and returns to the OFF state when released. Ideal for DIY electronics, control panels, prototyping, Arduino projects, robotics, and small appliances that require a reliable momentary input signal. The metal body ensures long-lasting performance, while the included locking nut and washer provide secure mounting on enclosures or panels.

Features:

• Momentary action: press to turn ON, release to turn OFF

• SPST (Single Pole Single Throw) normally open configuration

• Mini push button with red cap for clear visibility

• Strong metal threaded body for secure panel mounting

• Includes locking nut and washer for easy installation

• Suitable for low-voltage DC electronics and control circuits

• Smooth tactile response ideal for frequent press operations

• Compact size perfect for tight spaces in DIY or commercial projects

• Not designed for foot switch or heavy-load switching

• High durability for long-term use in electronic builds
