No matter how demanding the environment, HEPâs reputation for lasting durability shines through every component we supply. Our selection of electrical switches embodies this commitment, giving Cowan customers rock-solid reliability whether theyâre controlling heavy machinery, lighting systems, or precision instrumentation. Each switch is engineered from premium materials, rigorously tested for high-cycle endurance, and sealed against moisture, dust, and vibrationâso the first flip feels as crisp as the thousandth.
Pair that rugged build with intuitive installation and a compact, versatile design, and you get performance that quietly outlives ordinary hardware while streamlining your workflow. From momentary push-buttons to multi-position toggles, HEPâs range of electrical switches empowers you to elevate safety, efficiency, and confidence in every application, on the bench or in the field.
FAQs
What makes your lasting-durability electrical switches different from standard models?
Our switches are moulded from UV-stabilised, impact-resistant polycarbonate and use silver-alloy contacts mounted on a solid brass bridge. Each unit is cycle-tested 40,000 timesâwell above the AS/NZS 3133 requirementâto ensure reliable operation for decades. The faceplates carry an IK08 impact rating and an IP54 ingress-protection rating when used with the supplied gasket, making them resistant to dust, moisture and accidental knocks common in busy homes or commercial sites.
Are these switches suitable for Cowanâs climate and environmental conditions?
Yes. Cowan experiences wide temperature swings and periodic humidity, so our switches are engineered to operate from â25 °C to 55 °C without deformation or contact corrosion. All metallic parts are electro-plated to resist rust, and the plastic housings incorporate anti-fungal additives to prevent mould growth in damp areas such as laundries and semi-enclosed patios.
What kind of warranty do you provide and what is covered?
Every lasting-durability switch is backed by a 10-year manufacturerâs warranty that covers mechanical failure, contact wear, faceplate cracking or discolouration under normal use. If a switch fails, simply return it to our Cowan branch or an authorised reseller with proof of purchase and we will repair or replace it at no cost, including standard labour for removal and re-installation.
Can I use these switches in both residential and commercial projects?
Absolutely. The range is rated at 16 AX / 250 V AC and complies with AS/NZS 3133 for both residential and commercial installations. They also meet IEC 60669 for international projects. The modular grid system allows you to mix rockers, dimmers and USB outlets on the same plate, making them suitable for homes, offices, workshops and light-industrial facilities around Cowan.
Do the switches require any special maintenance to remain durable?
Routine care is simple: wipe the faceplate with a soft cloth dampened in mild soapy water and dry immediately. Avoid abrasive cleaners, solvents or high-pressure hoses that can compromise the protective coating. Once a year (or during any electrical audit), have a licensed electrician check terminal tightness to maintain low contact resistance. No other servicing is necessary.
Will installing these durable switches affect my energy consumption?
Mechanical rocker switches consume no standby powerâwhen they are off, they create an open circuit with zero energy draw. Because we use low-resistance silver-alloy contacts, voltage drop across the switch is minimal (<50 mV at full load), which helps prevent wasted energy in high-current appliances. Therefore, upgrading to our lasting-durability range will not increase your electricity bill and may slightly improve overall efficiency.
