The 3-Pin Momentary Roller Lever Arm Micro Limit Switch is a compact, high-precision mechanical switch designed for accurate position detection and limit control in industrial and automation applications. This SPDT (Single Pole Double Throw) micro switch offers both Normally Open (NO) and Normally Closed (NC) contacts, making it versatile for various electrical and mechanical setups.
With a momentary action mechanism, the switch activates only when the roller lever is pressed, automatically resetting once released. The durable plastic housing and metal roller arm provide reliable operation and long service life even under continuous use. Rated for AC 250V 5A, it is ideal for controlling relays, motors, and circuits in machinery, robotics, and DIY electronics.
