Miniature Microswitch with Lever SPDT — 1A @ 125VAC, Snap-Action, PCB Mount (5-Pack)

Miniature Microswitch with Lever SPDT — 1A @ 125VAC, Snap-Action, PCB Mount (5-Pack)

These miniature SPDT microswitches with levers are a light-duty snap-action switch for limit switch, end-stop, and position detection applications. The lever arm extends the actuation point away from the switch body, allowing the switch to be triggered by a moving part, cam, or object without direct contact with the switch body. Three terminals (C, NO, NC) provide both normally-open and normally-closed contacts from a single switch. Rated 1A @ 125VAC for logic and light-duty power switching. Pack of 5.

SPDT Terminal Functions

• C (Common): Always connected — connect your signal or power here
• NC (Normally Closed): Connected to C when lever is NOT pressed — opens when lever is depressed
• NO (Normally Open): Disconnected when lever is NOT pressed — connects to C when lever is depressed

1A vs 2A Microswitch — Which to Choose?

• 1A version (this listing): Light-duty, lower cost — for logic signal switching and low-current applications
• 2A version: Higher current rating — for switching small loads directly (LEDs, relays, solenoids)
• Both have identical body dimensions and lever length

Typical Applications

• 3D printer end stops: X/Y/Z axis limit switches for homing and travel limits
• CNC machine limits: Axis end-stop detection for CNC routers and mills
• Robot bumper switch: Collision detection for mobile robots
• Door / drawer position: Detect open/closed state of doors and drawers
• Logic signal switching: Microcontroller input trigger via lever actuation
