Embodiments of the present disclosure provide a flexible conductor for connecting a main blade and a base of a disconnector. The flexible conductor includes a first portion and a second portion, the first portion is fixed to the base and adapted to bend in a first plane in response to a rotation of the main blade about a first axis; and the second portion is connected to the first portion and fixed to the main blade, the second portion adapted to bend in a second plane substantially perpendicular to the first plane in response to twisting of the main blade about a second axis; wherein the flexible conductor is operable to maintain an electrical connection between the main blade and the base when the main blade rotates and twists with respect to the base to open or close the disconnector.

Disclosed is a rotary bridge micro-switch. The rotary bridge micro-switch comprises an insulating base, wherein a first terminal, a second terminal and a third terminal are arranged on the insulating base and are spaced from one another by the insulating base; and the insulating base is rotatably connected to a conducting plate having one end abutting against the first terminal. The rotary bridge micro-switch further comprises a spring having two ends respectively connected to the other end of the conducting plate and the insulating base. When the spring is not compressed, the first terminal is connected to the second terminal through the other end of the conducting plate. When the spring is compressed, the first terminal is connected to the third terminal. The rotary bridge micro-switch can be pressed to realize switching between two circuits.

A safety lockout device can include a main body, a receiving portion of the main body configured to receive a portion of an arm of an electrical switch, and a locking portion of the main body configured to be inserted into a receiving portions of the electrical switch.

Rotary switch (1, 101) comprising: a rotor (15, 115) supporting at least one electro-conductive rotary contact bridge (19, 119); a plurality of stationary contacts (21, 121); a housing (3, 103) accommodating the stationary contacts and the rotor. The housing comprises a plurality of sides (5, 105) extending between a top side and a bottom side. At least two of these sides (5, 105) are provided with access openings (62, 62) providing access to an associated stationary contact. These sides make an angle with each other. The housing may for example be rectangular.
