A medium voltage switching pole includes: a fixed contact of a vacuum interrupter; a movable contact of the vacuum interrupter; a piston; at least one electrical contact; a first terminal; and a second terminal. The fixed contact is fixedly connected to the first terminal. The movable contact is fixedly connected to the piston. The piston moves within the second terminal along an axis. The at least one electrical contact makes an electrical connection between the piston and the second terminal. An outer surface of the piston and an inner surface of the second terminal are arranged such that: when in an open configuration the fixed contact and movable contact are separated, at least one first radial line perpendicular to the axis extends through locations of the at least one electrical contact, and a first distance along the at least one first radial line extends from the outer surface.

The present disclosure proposes acompact electromagnetic push switch assembly with integration of an electromagnetic coil to push switch that can be directly fixed to the panel without any extra items. The cost and space required in order to make electrical panels and starters are reduced and further provide automation in domestic and industrial automation areas. A compact electromagnetic push switch assembly 100 comprises of a switch section 101, an operating member 102, a primary rod structure 103, a secondary rod structure 104, a spring 105, an electromagnetic coil 106, and a control unit. The contactors and relays in pumps or motor controllers for tripping required items are also replaced with 1 Amp to 40 amp relays and the push switch is designed to operate with any required voltage and Amps with AC or DC supply. The electromagnetic push switch is used in domestic, industrial, agriculture, hospitals, etc.

A portable electronic device includes a first body, a second body, a switching mechanism, a spring and a sliding mechanism. The first body includes a base and an input module slidably disposed on the base. The second body is pivoted to the base of the first body. The switching mechanism is disposed at the input module and is configured to switch an engaging relationship between the input module and the base. The spring is disposed at the base and abuts against the input module. The sliding mechanism includes a rack and a gear set engaged with the rack, wherein the rack is mounted to the input module and the gear set is slidably disposed at the base. The input module is pushed by the spring to slide relative to the base, and the rack slides relative to the base synchronously with the input module.

An operation device includes a movable member that is movable within a predetermined range, and a restriction member that is disposed in a state of being movable in a movable direction of the movable member, that restricts the movable range of the movable member by coming into contact with a contact surface of the movable member in the movable direction, and that can be switched between a state of being in contact with a first range of the contact surface and restricting the movable range of the movable member and a state of being in contact with a second range, the second range being different from the first range, of the contact surface and restricting the movable range of the movable member.

A disconnector having a stack of modular contact boxes surmounted by a snap-action switch box, each modular contact box including a rotary contact and two fixed contacts which are accessible from the outside. The switch box further includes a driven indexing element which is rotatably associated with a spindle loading support and at least one spring connected between the two in order to load them elastically with respect to each other following a mutual rotation about the central axis. The disconnector has a single actuation rod which passes through all the modular contact boxes coaxially to the central axis and is fixed in rotation to all the rotary contacts.

A gear structure and a dimmer and speed control switch, wherein the gear structure includes a plurality of positioning grooves and a gear switching component, and the plurality of positioning grooves are sequentially spaced apart on the housing; the gear switching component is movably Installed on the housing, it includes a positioning component and a biasing component connected with the positioning component. The positioning component has a first position that is positioned and matched with the positioning groove and a second position separated from the positioning groove. The biasing component applies a biasing force on position component that moves it toward the first position, the gear structure mentioned above can ensure accurate gear positioning during the operation of the dimmer and speed control switch, and is not prone to misoperate, which is convenient for users, and coordinated positioning grooves and positioning parts have the advantage of simplified structure.

A device includes a transmission assembly having a first override clutch. The first override clutch is used especially for transmitting a torque between a first coupling partner and a second coupling partner. The first override clutch engages and disengages in accordance with a change in the load flow between the coupling partners. A freewheeling member which is associated with the first override clutch neutralizes the engagement between the coupling partners. The neutralization is, in particular, temporary.

A vehicular operating device includes an operating member manipulated to swing, a slider slidably fitted in a holding bore, a cam surface positioned in front of the slider, and a helical compression spring pressing the slider into pressure contact with the cam surface. The metal-made slider includes a first outer peripheral surface with a diameter being smaller than an inner diameter of the helical compression spring, and a guide portion with an outer diameter allowing the guide portion to slide along an inner peripheral surface of the holding bore. A resin-made annular spacer having an outer diameter substantially equal to that of the guide portion is fitted between the guide portion and the helical compression spring. The helical compression spring biases the slider through the annular spacer. The annular spacer holds the helical compression spring in a state not contacting the first outer peripheral surface and the guide portion.
