An electrical contactless switch that includes a housing, a moveable element and a magnetic field sensor. The moveable element is made of a ferromagnetic material and is slidably mounted in the housing. The moveable element is adapted to move relative to the housing between a resting position and an engaged position, the moveable element is elastically biased towards the resting position. The moveable element includes a plurality of magnetized legs spaced from each other and at least part of the magnetized legs is slidably guided in the housing. The magnetic field sensor is secured to the housing and positioned to face the plurality of magnetized legs. The magnetic sensor is configured to detect a magnetic field generated by the magnetized legs as the moveable element is in the engaged position. The moveable element is closer to the magnetic field sensor in the engaged position than in the resting position

A reclosing switch capable of stably opening and closing, including a bracket, a permanent magnet moving core, a driving member, a linkage assembly, a limit assembly, an opening assembly and a contact mechanism. The permanent magnet moving core is configured to provide a force to drive a magnet to move axially along the permanent magnet moving core. When closing the switch, the driving member applies a pressure to the linkage assembly to drive the limit assembly to limit driving member. The opening assembly is configured to provide a force to push the limit assembly to reset, so as to release the driving member. The magnet is provided with a transmission member for connection with the contact mechanism. The contact mechanism is configured to contact with contacts in the switch.
