Description: High quality connected cable, it can withstand 2A current, 300V voltage. Using 22Awg wire and copper wire is very thick. The temperature range of the insulating layer is very wide, and it can reach 80 degrees. It is not easy to break, the plug is also convenient, the other side of the plug is well integrated, directly inserted can be used. Red wire is connected to VCC(ramps of +). Black wire is connected to ground (ramps of -). Green wire is connected to signal (ramps in s). Specification: Material:PCB Plastic Size:42x18mm Cable length:70cm Wire type: 22AWG Working voltage/current: 300V/2A Analysis of the principle of mechanical switch: The 1 end: power supply (VCC) The 2 end: ground (GND) The 3 end: connect with 2, you can not use it The 4 end: signal (SIGNAL) When the obstacle is not touched, the signal end is connected to the power supply, and the high value, that is, 1. When contact obstacles, the signal end is connected by a mechanical switch to a low level, that is, 0. According to the above logic, you can set the trigger at a low level, at this time the MCU receives a low level (1) and controls the motor to stop turning. Package Includes: 1x Limit Switches 1x 3 Pin 70cm Cable Note: Under normal conditions, at least 3 mechanical switches are required
