Push Button Switch — Momentary, Normally Open (NO), SPST Key benefits Provides reliable momentary control: the contact closes only while the button is pressed, ideal for reset, start, or test functions. Compact, easy-to-mount design saves panel space and simplifies installation in small enclosures. Clear visual options (red or black cap) help identify function at a glance and reduce wiring errors. Rated for AC 250V / 1A, suitable for low-power control circuits and signalling applications. Features and specifications Item: Push Button Switch Action type: Momentary (returns to open position when released) Contact type: Normally Open (NO) Pole: Single Pole Single Throw (SPST) Rated voltage/current: AC 250V / 1A Connectors: 2-pin Thread diameter: 6.9 mm (0.27 inches) — fits small panel cutouts and standard miniature mounting holes Cap diameter: 6 mm (0.24 inches) Pin spacing: 3 mm — compact footprint for tight wiring layouts Total size (max L x D): 25 x 9 mm (0.98 x 0.35 inches) Materials: Plastic and metal construction for lightweight durability Color options: Red, Black Compatibility and installation Designed for panel mounting using the 6.9 mm thread; easy to secure with a nut or retaining bezel. Two-pin connection simplifies wiring; suitable for direct wire or connector attachment in low-current circuits. Small overall dimensions (25 x 9 mm) allow use where space is limited — can be used on narrow front panels or compact enclosures. Practical use scenarios Control panels and machinery: Use as a momentary start, stop, or reset switch for control circuits that require a short-duration input. Electronics and DIY projects: Ideal for hobby boards, prototypes, or microcontroller projects that need a compact push button with a normally open contact. Small appliances and instruments: Use where a reliable, low-current momentary switch is required for signalling or user input. Why choose this switch Straightforward specification and compact form factor make it easy to integrate into existing designs. The normally open, momentary action gives predictable behavior for user-activated functions. Suitable for a wide range of low-power applications thanks to the AC 250V/1A rating and robust plastic/metal build. What to check before installation Confirm the AC 250V/1A rating matches your circuit requirements. Verify panel hole size and clearance for the 6.9 mm thread and 25 x 9 mm overall dimension. Ensure your wiring method accommodates 2-pin connectors and 3 mm pin spacing.
