The tilt and tip-over switches and motion sensors are available as mercury metal and our patented non-mercury metal
(patents #5.209.343 and #5.332.876.). Tilt switches are used to
sense movement (tilt) of a device above and below a horizontal axis. Some applications include: level controls, appliances,
security alarm systems, toys and games, float switches and
water treatment equipment, portable lamps, PC anti theft
devices, vending-machine alarms and machinery security
systems.

Optical switches are the best choice for liquid level detection.
They work by emitting a beam of infrared light within a prism
and detecting the reflection of the light. When fluid covers the
prism there is a change in the amount of light received and this
triggers the switch. The optical switch has no moving parts and
the on board electronics are completely sealed. These switches
are ideal for tank applications where high pressure water is
used for cleaning. Optical switches out perform conventional
float switches in these applications.

A reed switch consists of two ferromagnetic and specially
shaped contact blades (reeds) positioned in a hermetically
sealed glass tube in a protective atmosphere. The plated
contact surfaces are isolated from the outside environment,
which protects the contacts from contamination. Reed switches are available as form A (normally open), form C (changeover), and form B (normally closed). They are operated using
a magnetic field generated by either a permanent magnet
or current-carrying coil. Applications include sensors, relays,
pulse counters and security devices.
Conceptually, an acceleration sensor behaves similarly as a
tilt switch. When the sensor experiences acceleration the unit
registers a change of state. Our acceleration sensors can be
used to measure vibration on cars, machines, buildings, process control systems and safety installations. They can also be
used to measure seismic activity, inclination, machine vibration, as well as dynamic distances.
Float switches are designed to fit into tanks or reservoirs containing fluids. They are used to monitor liquid levels by opening or closing when a desired action point is reached. They
are operated by a magnet fitted into the float assembly and
a Reed Switch fitted into the stem of the float body. A variety of types are available using mercury and non-mercury tilt
switches and, also, permanent magnets and reed switches.
Common applications include sumps, pump-control systems,
bilge pumps, below ground vaults and irrigation systems.

We manufacture a wide range of proximity switches that use
either reed based, Hall effect or GMR technology. A reed based
switch is activated by a magnetic field pulling the contacts
either apart or together. Hall effect and GMR switches use
electronic sensors and require a power supply to operate. The
benefit of an Electronic proximity switch is that an LED can
be fitted to show the state of the switch. These switches are
very sensitive. They can detect a ferrous metal from greater
distances than reed based switches.
The new range of alarm and security switches are a cost effective solution for your security needs with an extensive product range that includes: recessed cylindrical contact switches
that can be easily installed into door frames. There are robust
Aluminium switches for shuttered loading doors or safety
guards. Also, adjustable plunger switches and tamperproof
draw switches.
A smart sensor has multiple sensors and multiple processing
techniques to obtain and transmit more information than one
could achieve from independent sensors. Smart sensors are
extremely universal. They could be used in anything from consumer products to the automotive industry. Here at Comus
International we customize our products to your specification.
Whether it’s changing reaction time, g-force, or tilt control,
our line of programmable sensors can give you the versatility
needed for your application.

• Dry Reed Relays
• Mercury Wetted Relays
• High Voltage Reed Relays
A Reed relay consists of a reed switch and coil fitting into a
housing which could be plastic, metal or moulded. Reed relays
generally have a faster response time than electro-mechanical
relays, lower coil consumption and are smaller in size. Furthermore, the switch is sealed in a dry inert atmosphere preventing the ingress of contaminants.
High voltage relays have outstanding performance in insulation and stand-off voltage. Energizing the coil operates a reed
switch causing the contacts to open or close.

Solid State Relays (SSR) manufactured by the Comus Group
of companies are sold around the world. The advantage of
having no moving parts, means that solid state relays have
an almost unlimited life expectancy when compared with
electromechanical relays. With no mechanical parts there is
no contact bounce, no spark and no mechanical wear making
solid state relay the natural choice in working environments
where these features are important.

Pressure switches are a vital part of many systems for example
Air compressor switching, Hydraulic switching of machinery,
gas leak detection and medical equipment. With a mechanical
life of at least 1.5 million cycles our switches out perform all
others and can be relied on for many years. They come in a
variety of thread sizes, pressure ranges and connection types
with either a factory set pressure or field adjustable and we
offer full customization to ease integration into your specific
product.
Comus International is dedicated to
providing quality solutions for your switching and
sensing applications.

We have a vast range of magnets available from low cost Ferrite magnets to advanced Neodymium based magnets. Neodymium have a strong polarized magnetic field and a usable
temperature of up to 130°C. Because Neodymium magnets
have low corrosion resistance our magnets are Bright Nickel
plated, we can also offer Zinc and Tin plating and powder
coating in various colours. For temperatures up to 550°C we
can supply Alnico and Alcomax magnets that have a good corrosion resistance and can be cast into more complex shapes
than other magnets.

Motion sensors are very similar in design to tilt switches; in
fact, some tilt switches are used as motion sensors. The sensor will be in one condition (open or closed) at rest. When it
is subjected to motion it will continually change state as long
as it remains in motion. Some common applications include:
anti-theft devices, man-down alarms to detect non motion,
smart appliances to turn off power when not in use and portable equipment to do the same.
