Mechanical limit switch with cable

This mechanical limit switch is suitable as a limit or reference switch for 3D printers and plugs directly into a RAMPS 1.4 board. It also suits other Arduino projects, for example as a door contact for an alarm system. A red LED lights up when the switch is actuated. The output is then pulled to 0 V, no additional pull-up resistors are needed.

Recommended alternative without contact: Optical limit switch light barrier with cable

Recommended Accessories:

• RAMPS 1.4 Control Board Arduino Mega Shield for RepRap

Features:

• Lever microswitch on a circuit board, circuit based on the MakerBot design
• Red LED lights up when the switch is actuated
• Pull-up resistor on the board, disable pull-ups in the firmware
• Mounting holes on the board
• Compare the wire colours with the board's pinout before plugging in

Application Examples:

• Limit and reference switches on 3D printers
• Door contact for an alarm system
• Other Arduino projects
