A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force. Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles, and many other places for control of electrical circuits. They are usually rated to carry current in control circuits only, although some switches can be directly used to control small motors, solenoids, lamps, or other devices.There is a press key on the sensor. During a collision, the sensor outputs a low level signal as the button is pressed, and maintains high level when released.
The module comes with a JST PA SMT 3-Pin horizontal sticker and a buckle socket. Also, a JST PA to DuPont female 3-Pin single-head wire is offered to facilitate wiring. Length: 210mm, buckle attached.
