This switch is open (off) when still state， when the external force to the touch and to achieve a proper shaking force， or speed of movement to achieve suitable (partial) of the heart， conductive pin will temporarily conduction (on) state， change electrical property when the external force disappears electrical property open (off) is resumed.

Circuit may have to choose trigger sensitivity which are suitable for the sensitivity of the switch.
