Electrical Connectors
What is a Connector?
A connector is an electromechanical device used to join two electrical parts together, generally this would be connecting a cable to a system or cable to another cable within an electrical circuit. There are many different types of connectors that can accomplish this. They can be used to connect power, data and fibre and can come in different shapes, sizes and materials. They can also be waterproof, dustproof and heat proof to various industry ratings. Our sales team is ready to help you with any queries.
What Do We Supply?
We offer a broad range of electrical connectors, including:
Appliance couplers
Hazardous area connectors
'Buccaneer' sealed connectors
General purpose connectors and accessories

The TCS43 is a microminiature SMT tactile switch designed for high-performance applications requiring compact size, reliability, and precise haptic Feedback. With a footprint of just 4.2 × 3.2 mm and a low profile of 2.5 mm, it enables space-efficient PCB layouts without compromising usability.
The switch offers three actuation force options (180 gf, 250 gf, 400 gf; equivalent to 1.76 N to 3.92 N), allowing engineers to fine-tune the user experience depending on application requirements. Its mechanical lifetime of up to 100,000 cycles ensures long-term reliability, even in demanding environments.
Electrical performance supports low-power designs (10 µA to 50 mA, 1–12 VDC), while contact resistance remains ≤100 mΩ for stable signal integrity. The device operates reliably across a wide temperature range (-40 °C to +90 °C), making it suitable for both consumer and medical applications.
Typical use cases include user interfaces such as on/off switching, menu navigation, and parameter selection in high-end consumer electronics, home automation systems, IoT devices, and medical equipment (e.g., blood pressure monitors, ventilators).
The TCS43 combines compact design, robust performance, and flexible actuation characteristics making it an ideal choice for next-generation interface solutions.
