Marquardt 1065 Micro Switches: Flawless Operation in Harsh Environments

Marquardt 1065 Micro Switches: A Strategic Solution for Modern Applications

Marquardt has introduced a game-changing type of micro switch featuring self-cleaning contacts (wiper contact) and an IP67 rating, specifically designed for harsh industrial settings, outdoor applications, and medical tech.

Compact and quiet, Marquardt micro switches are the perfect solution for reliable position sensing. With high durability, long life, and easy integration, they reduce both failure rates and maintenance costs, making them the go-to solution for projects that demand top-tier performance.

“When it comes to switches, especially micro switches, Marquardt is a name everyone trusts for quality and reliability. I’ve heard it countless times: ‘The issue is not with the switch – it’s a Marquardt.’ That really speaks volumes of their reputation. These micro switches are a standard in cars from major global brands, proving just how durable and reliable they are in even the toughest conditions,“ says František Ďuríšek, product specialist at SOS electronic.

Key Benefits of Marquardt 1065 Series Micro Switches 

• Compact size - from 13 x 5.4 x 18* mm (depending on type and configuration)
• Lifetime - 200,000 cycles
• SPDT contact configuration
• 1075.xx switches feature SPDT with 3 positions
• Double contacts for added reliability
• Self-cleaning contacts
• Contact resistance in closed state < 0.5 Ω
• Current through contacts 1 - 100 mA
• Ambient temperature range –40 to +85 °C
• Dust and water ingress protection - IP67 rating

Unique Features of Marquardt 1065 Series Micro Switches 

• IP67 rating prevents water ingress and ensures reliable operation even in the presence of moisture and frost
• The design ensures that contacts slightly rub together when switched, eliminating the risk of oxidation, especially during extended periods of inactivity
• The 1075 series offers 3 switching positions

“You might be wondering what makes these micro switches stand out in an age of semiconductor-based, contactless position sensors – whether capacitive, inductive, or optical. The biggest advantage is their zero energy consumption when idle. Plus, they operate on a simple, reliable principle – an electromechanical contact that’s either connected or disconnected,“ continues Ďuríšek.
