ABSTRACT:
A stopping device with a switch of the invention includes a bolt with a head portion, a control signal generating device situated in a bolt through hole of the bolt, and a sliding member. The sliding member includes a shaft slidably situated in the head through hole, a flange attached to the shaft and having a second stopping face facing a first stopping face of the head portion, and an end portion extending from the flange to contact an object to be detected. After the object contacts the end portion, until the second stopping face abuts against the first stopping face, the control signal generating device produces a control signal. A sealing device is installed between the head portion and the sliding member. Thus, dustproof and waterproof effects can be obtained.
