A disconnecting switchgear has three mutually exclusive positions II-0-I, with position II energizing the load circuit, position 0 de-energizing the load circuit and position I grounding the circuit, which reduces the electrical risk when interacting with an electrical panel. The switchgear includes a control interconnected with a body, where the control includes a gripping mechanism with an electrical labelling element, an extension mechanism, a locking mechanism and indicator labels; the body includes a group of external electrical conductors or connection terminals, a group of internal electrical conductors or poles, an earth short-circuit electrical conductor, displays of electrical quantities, luminous indicators, and sight glasses for viewing moving poles; electrical conductors and electrical contacts interconnected with a drive shaft and the latter to a power-transmission mechanism.

Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.

A connection verifier, including a collar, a circuit board non-rotatably connected to the collar, the circuit board including at least one terminal, a switch rotatably connected to the collar and arranged to contact the at least one terminal, the switch including at least one finger extending in a first axial direction, and an indication device arranged to activate when the switch contacts the at least one terminal.

A power supply system includes a switch unit and an operating mechanism. The switch unit includes: an arc-extinguishing functional component, a fixed contact assembly, a moving contact, and a first magnet assembly. The arc-extinguishing functional component is located inside the arc-extinguishing functional component and can move relative to the fixed contact assembly. The operating mechanism controls the switch unit to be opened when receiving a switch-off signal, so that the moving contact is separated from the fixed contact assembly. An electric arc is formed between the moving contact and the fixed contact assembly in a separation process. Directions of at least some magnetic induction lines of the first magnet assembly intersect a current direction of the electric arc to drive the electric arc to move towards the arc-extinguishing functional component. The first magnet assembly includes a first magnet and a second magnet that are spaced apart.

A rotary switch having a fixing body, a rotating body disposed in the fixing body, a cover coupled to an upper portion of the fixing body, and a first elastic body positioned under the cover to contact a plurality of protrusions formed on the rotating body is provided. The protrusions of the rotating body protrude in a side direction and radial direction of the rotating body to improve a rotational operation feeling and the quality of a rotational sound.
