4G-series cam switches are low voltage switches, designed according to the latest knowledge about switchgear and using the achievements of modern engineering. Only high quality insulation and contact materials have been used in these products. Basic components and units are standardized and
mass-produced, making it possible to make switches performing any switching programs, and short delivery terms.
Switches can be produced in many versions and have various applications.
They conform all requirements for low voltage switches in industry, mining, shipbuilding, etc. They can be used as hand-operated switches in transformer stations, control switchboxes and boards, switchgears made of cast iron or other metals, welding machines and similar devices.
4G series switches are characterized by small external dimensions, powerful switching capabilities, long contact life and high mechanical stability, and resistance to short-lasting overloads. When additionally protected with fuses, they are also resistant to dynamic effects of short-circuit currents.

Application

Cam switches can be used in main and auxiliary circuits, especially:
  • as switches for electric motors for switching and controlling the drives with single- and three-phase motors, as star-delta switches, reversing switches and switches for changing the rotational speed, etc.,
  • in auxiliary, controlling, signalling and measuring circuits, manufactured according to the required switching program,
  • as breaker switches, change-over switches and tap switches, for example for transformers and electric welding machines,
  • as switchgroups, for example to connect resistors and heating elements,
  • as change-over switches working as push-buttons with automatic returning to an off position,
  • as switch disconnectors.

Construction

Depending on the switching program, every cam switch consists of a certain number of switching elements, which can be easily assembled together. Switching elements' bodies are made of plastics based on melamine, especially
resistant to the effects related to creep currents and electric arcs. A switching element has one or two current circuits arranged at the angle of 180º and equipped with contact with a double contact gap. Each of them consists of two stationary contacts and one movable contact bridge. The contact bridge is switched on (pressed) by contact springs, and opened by a cam inside the switching element. The cams in individual switching elements
are firmly coupled together, ensuring practically simultaneous switching (on and off) of all contacts. Thanks to the double gap contact assembly and contact tips made of special alloy containing silver and very resistant to effects of an electric arc, high switching capabilities and contact life have been obtained. Good clicking mechanism of a motion work ensures unfailing switching of moving contacts in respective fixed positions. The power springs of the clicking mechanism are different, depending on the number of the switching elements.
 
According to individual requirements, cam switches can be made with the switching angles given in table 2.

Special stops are used to fix proper positions. Switching elements, driving mechanism and a rear plate (mounting plate) are connected into one unit with insulating bolts.
Special versions of cam switches can have more than 12 switching elements.
Sub-assemblies

Front plate
Complete front plate consists of:

  • a front plate with a place with black frame for a text; - an indicating plate cover (transparent),
  • indicating plate (under the cover, standard version is white with black signs).

According to requirements, this plate can be black, yellow or silver.

Knob
The knob is used to control the switch. Black is a standard colour. According special to requirements, the knobs can be supplied in red colour.
