Title:
SWITCH DEVICE
Document Type and Number:
Japanese Patent JP2016115556
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switch device which is never turned on multiple times for a vibration occurring once, and capable of generating a switch signal reliably even if the material or the structure of an object changes.SOLUTION: A switch signal generation circuit 11 is configured so that the threshold can be changed. Consequently, even if the material or the structure of a wall W changes, the threshold can be set correspondingly, and the switch signal can be generated reliably. Furthermore, when the switch signal inputted from a switch signal generation circuit 11 changes from off state to on state, a switch signal correction circuit 12 holds the on state regardless of the state change of the switch signal during a preset holding time, and outputs a new switch signal. Consequently, such a situation that the switch signal is turned on multiple times for vibration generated once can be suppressed.SELECTED DRAWING: Figure 1
