Product Description The 10T85 Miniature Lever Switch is a high-performance snap-action limit switch designed for precision control in compact spaces. It features a Single Pole Change Over (SPCO) configuration, meaning it has one common input and two output terminals (Normally Open and Normally Closed). The "10T85" marking indicates its high-temperature tolerance, rated to operate reliably in ambient temperatures up to 85°C. With a durable black plastic housing and a responsive carbon steel lever arm, this switch is a staple in the Robogears Pvt Ltd inventory for use as a bump sensor in robotics or a safety limit switch in home appliances.

Key Highlights

Change-Over Capability: Offers both NC (Normally Closed) and NO (Normally Open) logic, giving you total flexibility in how your circuit responds to the lever being pressed.
High Temperature Resilience: Rated with the 10T85 standard, ensuring the internal spring and casing maintain their mechanical properties even in warm industrial environments.
Extended Life Cycle: Built for longevity with a mechanical life of approximately 10,000 to 50,000 cycles, making it ideal for high-frequency switching tasks.
Miniature Footprint: The ultra-compact size (approx. 20mm x 10mm) allows for easy integration into tight enclosures, 3D printers (as end-stops), and small electronic projects.
Precision Snap Action: Provides a tactile and audible "click" when activated, ensuring a fast and clean electrical transition to prevent arcing.

Technical Specifications

Prototyping & Installation Tip (Robotics Bump Sensor) For robotics applications at Robogears, use this as a Bump Sensor. Connect the COM (Common) pin to Ground and the NO (Normally Open) pin to a digital input on your microcontroller with an internal pull-up resistor enabled. When the robot hits an obstacle, the lever arm will trigger, pulling the pin LOW. To prevent "switch bouncing" (multiple false signals in a few milliseconds), add a small delay in your code or a 100nF capacitor across the switch terminals.
