A switch may include a movable board and a pole board having an inner surface on which a fixed contact point is exposed, the inner surface facing the movable board. A movable contact point may be supported by the movable board and may include a plurality of contact pieces making resilient contact with the inner surface of the pole board. The switch may also include an output terminal corresponding to the fixed contact point. The movable contact point and the fixed contact point may come in contact with each other when a position of the movable contact point is changed via a displacement of the movable board. The fixed contact point and the output terminal may be connected via a board having a disconnection detection circuit. The board may be enclosed in an insulating seal material.

A method and a system for checking the correct rail position of a guide member of a guided vehicle. The system is based on the use of an electrical switch designed to cooperate with a guide member of the vehicle guided by at least one guide rail. The switch has two states, respectively a first state and a second state. In one of the states the electrical switch is open and in the other state the electrical switch is closed. The switch is mounted on a load-bearing structure such that it is able to interact with the guide member. The switch is able to switch from the first state to the second state by interacting with at least one part of the guide member.

A waterproof switch device includes: a switch member including a body portion and a movable portion; an operated portion that is a shaft member having a distal end exposed from an opening provided in an exterior member of an electronic apparatus and a proximal end connected to the movable portion, the operated portion including a flange portion extending in a radial direction; a waterproof cover made of elastomer material; and a retaining member including an opening portion through which a part of the operated portion closer to the distal end than the flange portion can pass but the flange portion cannot pass, the retaining member being disposed farther inward from the exterior member than the waterproof cover.

An electrical assembly including a grounding mechanism and an electrical device, the grounding mechanism including a support longitudinal member and a switch contact member, the switch contact member arranged in or on the support longitudinal member, the switch contact member configured to be connected in use to ground, the electrical device including an electrical terminal, wherein the support longitudinal member is configured to be slidable between: a first position in which the switch contact member is separated from the electrical terminal so that the switch contact member is electrically disconnected from the electrical device and a second position in which the switch contact member is in contact with the electrical terminal so that the switch contact member is electrically connected to the electrical device.

An input device has a first electrode, a second electrode, and a third electrode. The second electrode opposes to the first electrode while being spaced apart therefrom. The third electrode is spaced apart from the first electrode and rotatably or slidably provided relative to the second electrode. By the third electrode being brought into contact with or spaced apart from the second electrode, an electrical state between the first electrode and the second electrode changes. Based on this electrical change, a rotary manipulation or a slide manipulation is detected.

A motor is generally described. The motor may include an armature and a coil. The coil and armature operatively receive power from a power source. The power induces magnetic fields in the coil and armature to drive the armature. When power is removed, the coils reverse polarity to inductively decelerate the armature.
