Discrepancy Switch

Discrepancy Switch NOVA Discrepancy Switch

NOVA NDCS Discrepancy Switch are used to control and monitor circuit breaker and disconnecting switches, and to display their circuit state in mimic panels and illuminated mimic diagrams. When the discrepancy lights up, that means that the position of the discrepancy switch does not match the pre-assigned circuit breaker . The luminous source is from an inbuilt high brightness LED lamp with amber colour.

Cam Switch

Cam Switch Rotary Switch NOVA Cam Switch Nova Cam Switches

Nova Cam Switch series NCS have been developed to the latest achievements in the field of switching devices through the application of high quality insulation material and contacts made from silver alloys.

Their advantages are high making and breaking capacities, electrical and mechanical endurance and small dimensions. The rotary cam switches are intended for multiple switching operations in main circuit as well as in auxiliary circuits.

Nova NCS series have three current ratings: 20A, 25A and 32A. All ratings has the finger proof terminal. The series comply with IEC 60947-3, IEC 60947-5-1.

Selector Switch

Nova Selector Switch Series are robustly designed to provide the switching of industrial equipment. It comes with a choice of 2 or 3 switching steps, and a variety of contact configurations. Custom contact configurations are available upon request.

Pilot Lamp

Nova Pilot Lamps are highly reliable pilot lamps that come in a variety of lens configurations, LED assemblies, and voltage options. These pilot lamps feature Low Voltage Glow Protection (LVGP) technology that prevents the LED from lighting up below their rated voltages.

These lamps feature:

1) Shock resistant design

2) High Brightness pure colour LED

3) Built in current limiting resistor and zener diode.

4) Customizable voltage rating

Push Button

Nova Push Buttons feature durable spring mechanisms. They come in both illuminated and non-illuminated options, while featuring various contact options. There are two button action options; alternate, and momentary. Customizable voltage ratings are available upon request.

Semaphore Indicator

LED Semaphore indicators are used to indicate the statuses of circuit breaker, and disconnecting or earth switches. These semaphores are mounted onto panel with mounting hole 22.5mm diameter. Operating status will be displayed in either red or green. They also feature long electrical lifetime of at least 100000 hours.


This miniature buzzer is used for general purpose alarm and warning applications. They are normally used in cubicles or control boxes for a wide range of applications which include: power distribution boards, LV. Switchgear, MV. Switchgear, panel boards or switch boards, and even in the control boxes of production machines.

Mechanical Hygrostat

This miniature buzzer is used for general purpose alarm and warning applications. They are normally used in cubicles or control boxes for a wide range of applications which include: power distribution boards, LV. Switchgear, MV. Switchgear, panel boards or switch boards even in controller box of production machines.

Timer Relay

Nova Timer Relays are designed for industrial, and machine control processes. They come in field selectable time ranges of 0.05 seconds, up to 500 hours, while featuring wide input voltages from 24 to 240 VAC/VDC.

Timer Switch

Nova Timer Switches are designed for industrial, home, and a variety of other applications.


Capillary thermostats are accurately and reliable designed to control temperature for domestic appliances and industrial equipments.

Nova thermostat (NTH-60 type) is an economic and reliable instrument, widely used in the relay & control panel, switchgear cubicle, main distribution board, control boxes, laboratory instruments and others. When it used, usually shall be combined with other products such as an electric fan and/or a space heater.

Space Heater

Nova space heater is an economical and reliable source of heat, widely used in the control panel, switchgear cubicle, main distribution board, control boxes and etc. When it used, normally shall be combined with other products such as electric fan, thermostat or hygrostat. Heat element is made of a mica strip heater and the flat resistance ribbon generates heat over a broad area. Nova space heaters feature rugged and modern design to fulfil the function of heating. The cover of the heater is made of zinc-coated steel and painted with epoxy black colour.

Electromagnetic Counter

Nova Electro-magnetic counters NEC series is designed to be used as the accumulative recorder of the electrical pulse signal in the system. It can equip with the secondary instrument to form the digital display instrument, which is widely use for calculation in various industries, such as the petroleum, chemical, textile, machinery, agriculture, food, printing and so on. After the electrical signal input to the counter, it will generate attractive power in the electromagnet, which will make the armature to drive the numerical gear to conduct decimal counting.

Line Lamp

NOVA NLL series line lamps or status lamps are panel mounted assemblies which are consist of the indicator housing, an internal LED lamp, terminals (at the rear side), and a lens. Applications include industrial control panels of all types, equipment indicating panels, status indicators and display lighting. The light source is from high brightness pure colour LED.

Universal Outlet

NOVA® universal outlet is made of a high impact-resistant thermoplastic face for single outlet and rugged design with metal for double outlet. Ideal for mounting in equipment cabinets where AC power is required, i.e. laptop computers, test equipment, electrical tools, etc.

Limit Switch

Limit Switches are operated by the motion of a machine part or presence of an object. They are used for controlling machinery as part of a control system, as a safety interlock, or to count objects passing a point.  A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection.

Industrial Power Relay

Industrial power relay of NOVANP403 series enable the high switching capacity up to 40 A, high contact force, minimum bouncing time, low power consumption with various choices of selectable coil voltage. Also their high degree of protection (IP50) ensures the reliable operation in tropical and/or salty ambient air condition.

These NP403 relays are an alternative choice which can be widely implemented to the power control circuit in industrial sector, electrical equipments, power stations, substations, railway and industrial plants etc.

Current Transformer

Current transformers are special transformers for the proportional transformation of high currents into direct measurable values. Their construction and physical operating principle enable an electrolytic separation of the primary circuit from the measured circuit, thereby providing a safety mechanism when switching on the measuring appliance in the even of a fault.

Service Lamp

Nova Service Lamps are intend for use in areas with limited space such as small cubicle or boxes. The lamp inside is E27 electronic control low energy consumption lamp(9-11W).
