Switch insert of electrical installation switch

FIELD: electrical engineering.

SUBSTANCE: switch insert of electrical installation switch with formed from first housing part (4) and second housing part (5, 7) switch housing, on which swinging switch lever (43) is rotatably and movably mounted. Swinging switch lever through an actuating protrusion, recessed in switch housing, acts on contact arm (38), there are at least two connecting terminals (19, 25, 31), which are equipped with at least one contact part (20, 32) and support contact arm and are configured for electrical connection with each other by means of contact arm (38), two connection terminals (19, 25, 31) are inserted into pockets of contact chamber on inner side of first housing part (4), on which there is centering rib (16), which locks contact arm (38) in pre-installation position between support (26) contact arm and centering rib (16).

EFFECT: preventing switch insert from falling.

SUBSTANCE: blocked device for a fast connection key in electrical mechanisms consists of an additional device (2), situated at the bottom end of a fast connection key (1) and connected thereto by a region (4) which gives the connection flexibility and allows displacement of the entire device (2) closer to the key (1) by pressing on or separation therefrom and return thereof to the initial position by ceasing the application of pressure which may be applied to the device (2) or to a hook (3), by which the device (2) ends at its bottom end. During rotary displacement of the key (1) and approach to the outer surface (6a) of the housing (6), the end hook (3) of the device (2), which makes up the blocking device, comes into contact with the bottom outer surface (9a) of the bottom protrusion (9), centrally symmetrical to the housing (6), while sliding thereon until said hook is fixed at the top edge (9b) of the protrusion (9), wherein the entire key (1) is fixed in a connection position.

EFFECT: preventing accidental displacement of the fast connection key, which leads to separation of the device from the housing and movement of the electrical mechanism into an off position.

SUBSTANCE: multifunctional electric mechanism is designed for use in applications of internal wiring and in cases of surface mounting and consists of case (1) fixed to support ring (56) and equipped with external operation key (16). Hollow internal area of case (1) comprises mutually replaceable sets of contacts (22, 23, 24, 30, 32 and 34) for realisation of various applications of mechanism as switch. Case (1) is characterised by side fixtures (2). Rocker (13) sends pressure applied to key (16), to rocking contact (21), and is characterised by two hinged joints (18) with a single rocking contact (21). Closed contact (23) of crossover switch is produced by means of soldering with soft solder, is provided with partition (53) as protection against electric arc generation. System is proposed for fixation of contacts, as well as a method of quick connection keys (11) blocking when used in structure of control signal lamp (5), contacts of which, due to its rotation from one position into another provide for the possibility to change its functioning between control signal lamp and illumination. Mechanism may be extracted from front part without necessity to remove a support ring (56).

EFFECT: provision of possibility for instant replacement of mechanism elements.
