HS-S31P, Collision Sensor

The HS-S31P, Collision Sensor switch module is essentially a micro snap-action switch, also known as a micro switch, which is an electronic switch activated by very small physical pressure. It can be directly connected to a single-chip microcomputer. It integrates the load resistor with the LED indicator. This makes it easier to test it. When physical pressure triggers the switch to close, the LED indicator on the board will light up. The principle of the collision switch is relatively simple, as shown in the following schematic diagram. When it is triggered to close by external force, the switch is closed and the module outputs a low level; when the external force is removed, the switch is opened and the module outputs a high level.
